I certainly don't have that option, but that could well be because I'm
using an analog monitor. I've also corresponded with an Nvidia rep through
their customer support channel, and they seem to be clueless about this new

Linux drivers have offered 10 bit support via XOrg for quite some years,
including desktop cards, however the software side is very scant and the
window manager side is worse. exrdisplay uses it, as well as several
commercial industrial imaging applications.
Windows as well has offered it for quite a few years, with similar issues,
although only via the industrial card support, not desktop.
Apple has entered now recently with hardware, but have again offered the
software side for several years.
AMD and NVidia both offer different feature sets. For example, NVidia
offers a "punch through" 30 bit mode that effectively lets an 888 mode
punch through a 101010 mode on a per window basis.
