So Bert loves to focus on Apple's decisions to be the first to drop support for
legacy standards, like the analog audio headphone connector on the new iPhone 7
models.
He never mentions all the technologies and industry standards that Apple adopts
first, like HTML5, HDR imaging in iPhone cameras, and now wide color gamut
displays and camera support.
The most significant news from Apple's event yesterday were in the iPhone
cameras and display. The dual camera system on the iPhone 7 plus breaks new
ground in image capture and processing; when I see a good article on this I
will post it.
The following article covers the wide color gamut announcements.

iPhone 7 and Apple's next Retina Display frontier: Wide Color
In 2010, Steve Jobs introduced a new leap forward in display resolution for
iPhone 4 that passed up the rest of the industry to deliver pixels virtually
invisible to the human eye. For iPhone 7, Apple appears to be making a similar
leap in the realm of "Retina Color."

Without a Wide Color display, this box only appears to be solid orange
Apple's new work on Wide Color results in lush, vibrant greens and vivid reds
that today's basic screens can't even reproduce. After seeing Wide Color at
work—it's currently available on new iMacs and the newest 9.7 inch iPad
Pro—regular displays look flat and lifeless in comparison, much the same way
that iPhone 4's debut of the Retina Display created a new "no going back"
milestone in users' expectations for modern mobile electronics.
The image above, created by Apple's WebKit team, appears to be just an orange
square on standard RGB displays. However, from a device capable of supporting
the DCI-P3 Wide Color Gamut, you can see a logo. The before and after display
of Wide Color images is even more impressive when viewing vibrant landscape
images.
This year, it appears Apple is set to again change expectations in the realm of
the colors that users see—and can capture—every day on their iPhones, despite
very little being talked about color accuracy and reproduction among mobile
device vendors outside of Apple.
It is, however, an emerging focus among HDTV vendors, who see Wide Color as an
essential component of High Dynamic Range TVs. Wide Color not just a hardware
issue; it connects to production, distribution and capture.
In the realm of TV, Wide Color is an industry effort. On mobile devices, it
will require integration between software developers and hardware makers. The
fact that Apple has already introduced Macs and iPads supporting Wide Color
underlines its unique ability to deliver new technology in ways that matter,
something that broadly licensed platforms—particularly value engineered
platforms like Google's Android—have struggled with.
Wide Color is part of what TV vendors are branding as "High Dynamic Range"
This all happened before
Prior to Jobs' launch of iPhone 4, a variety of Android phones—such as the
Motorola Atrix—were already being hyped for introducing higher resolution
screens: the Atrix boasted 960x540 pixels versus the original iPhone's 480x320.
There was some fudging involved to achieve that higher resolution: the Atrix
and other 2010-era Androids commonly used PenTile AMOLED, a cheaper display
technology that claimed a high pixel resolution despite actually supplying a
third less sub pixels (by arranging more greens and fewer reds and blues). As a
result, reviews described Motorola's Atrix as having "inaccurate colors and
poor viewing angles, not to mention practically unreadable text at its furthest
zoom."
Additionally, rather than using the extra resolution to enhance the quality of
the display, Android makers simply followed what PC makers had been doing with
extra pixels: stretching out the 'desktop' to expand across a larger display,
or scaling down the UI to fit more content on the same screen.
On PCs, higher resolution displays had typically been tied to the advancement
of incrementally larger PC monitors. On mobile devices however, adding more
pixels tied to a larger screen were resulting in bigger phones—with obvious
disadvantages. Further, higher resolutions were also making tap targets smaller
and scaling down text to the point where it became more difficult to
read.Apple's iPhone 4 Retina Display harnessed technical progress in a new
direction
Apple's iPhone 4 Retina Display harnessed technical progress in a new
direction: it kept the user interface at the same scale and increased the pixel
count four-fold, resulting in very crisp text and precise detail of everything
on the screen, rendering pixels virtually invisible.
In hindsight, Apple's strategy for resolution leap was obvious. However, it
wasn't immediately copied. Samsung's original Galaxy Note "fablet" debuted a
year after iPhone 4, but rather than similarly introducing a high quality,
retina-like display, it continued to use a subpixel-fudging, cost-effective
PenTile screen on a larger device, hoping users would be impressed with pixel
numbers rather than caring about how pixels or color on the screen actually
looked.
As Rasmus Larsen noted at the time for FlatPanelsHD, "a PenTile OLED panel was
recently introduced with the Samsung Galaxy Note, and we were not impressed. In
real world PenTile means loss of details and sharpness, as well as a
bluish/greenish tint around letters (depending on the background color)."
The site also called out Google's Samsung-built Galaxy Nexus, noting that "the
HD Super AMOLED display in the new Galaxy Nexus is not as awesome as it
sounds—unfortunately. And the reason that people do not call it a Retina
Display should seem much more obvious to you now that you know the underlying
technical architecture."
In the years since, Apple brought its Retina Display to iPad and to its Mac
lineup. TV makers have similarly advanced HDTV sets to support "4K," making
their displays four fold sharper in pixels rather than just larger. And of
course, the smartphone industry now generally follows Apple in making sharper,
not just larger, displays as well.
Wide Color: the new Retina Display of gamut
Once iPhone pixel density achieved Retina Display status, Apple didn't change
it again until it introduced larger screen sizes. As Android vendors have
learned the hard way, arbitrarily squeezing in "even more pixels" just for
bragging rights results in a new problem: a huge increase in display processing
tasks that slows everything down.
While iPhone 4's Retina Display involved less than a half million pixels,
today's largest iPhone 6/6s Plus has to wrangle over 2 million pixels. Higher
end Androids—such as Samsung's Galaxy line—pack in nearly 3.7 million pixels
into a similar screen size, but have historically opted to use a less powerful
Application Processor, resulting in poor performance.
Rather than following Samsung in an underpowered, overspecced resolution
numbers race, Apple has been working to improve future displays in ways that
will actually matter to its users. One primary result is Wide Color, a new
initiative to expand the color gamut of the display to cover more of visible
color spectrum captured by digital cameras.
That not only requires new display hardware, but also requires sophisticated
color management software. Apple first delivered Wide Color support in the 5K
iMac. This year, it expanded support to the new 9.7 inch iPad Pro.
Apple's new support for the DCI-P3 Wide Color Gamut results in an expanded
ability to reproduce more accurate color than the existing "Standard RGB" can.
The prevailing sRGB can't reproduce the most vibrant, vivid colors we can see.
Interestingly, many cameras capture RAW color data that simply doesn't show up
on today's sRGB displays.
The work Apple has done to support Wide Color in both hardware and software on
its 5K iMac is really an expansion of its ColorSync color management software
that already existed on Macs.
However, bringing Wide Color to iPad Pro involved creating new software support
for advanced color management in iOS, with backward compatibility to enable the
existing library of App Store titles to continue to work, and new frameworks
for developers to adopt to work with new 16-bit per color, Wide Color images.
The result of Apple's work on Wide Color on iPad Pro was hailed by Ray Soneira
of DisplayMate back in March. He described it as offering the highest absolute
color accuracy, the lowest screen reflectance for any mobile display, the
highest peak brightness for any full-size tablet for any picture level, the
highest contrast rating in ambient light and the smallest color variation with
viewing angle.
Soneira was impressed enough to predict that Apple could implement the same
Wide Color gamut and anti-reflection coating of iPad Pro on iPhone 7, noting
that this would improve its screen performance and readability in bright
ambient light.
iPhone 7 display: True Tone & Wide Color
Apple pretty obviously didn't complete all its work on Wide Color just for one
new model of iPad. Bringing support for Wide Color to iOS involved changes to
UIKit, Core Animation, Core Graphics, Core Image, ImageIO, SceneKit, SpriteKit
and WebKit—a major undertaking spanning much of the company's software groups.
Given the attention Apple devoted to Wide Color at WWDC, it seems quite clear
that Apple will also bring Wide Color, and likely a True Tone display (like the
new iPad Pro, below), to iPhone 7, resulting in more vibrant and accurate color
display—in apps, on the web, and even for users' existing photos—that buyers
will consider a significant advance and a reason for upgrading.
Both True Tone and Wide Color require extensive hardware and software
integration to work. Like support for Retina Display, it also requires some
attention from third party developers to make sure that the new changes are
supported in their apps. That indicates that Google and its hardware partners
will have a difficult path ahead in trying to close the color gap.
Thinking outside the dots
Today, Android phone vendors hoping to stand out in a crowded market face a
number of issues. Phone fragmentation—often related to the use of cheapest
possible components—results in compatibility problems and makes it more
difficult for Google, its hardware partners and mobile carriers to roll out new
features or patch existing flaws.
As noted by Phil Nickinson of Android Central, Samsung's Galaxy S7—often talked
about in the media as the equivalent to Apple's iPhone 6s—is actually a brand
name applied to "31 separate versions of the Galaxy S7" that Samsung sells
worldwide. Nickinson was writing about Android phone compatibility with Android
Auto, Google's version of CarPlay; regarding the 31 slightly different Galaxy
S7 models, he noted that "Some work. And some don't."

Samsung has also focused its attention on selling waterproofing claims that
literally don't hold water. Joanna Stern of the Wall Street Journal attempted
to carry that water herself in a piece that recommended phone buyers hold off
on iPhones but not wait for a new Galaxy S7, specifically citing
"waterproofing" as a key reason for buying a high end Samsung.
However, both Square Trade and Consumer Reports have called out Samsung for
inflating its claims of water resistance after testing multiple Galaxy S7
models that all failed to actually survive the dunk tank.
Apple's ability to introduce finished technologies that work as advertised and
meaningfully improve users' experience is also assisted by its global network
of retail stores, where users can experience leaps like 2010's Retina
Display—and this year's leap to Wide Color—for themselves.
