I agree here as I have some experience now on the process, but:
* In the case where RGB pixel spectrum is close to normative. Inexpensive LED
displays use blue + wide green-red spectrum diods that can’t separate green and
red well. Low class monitors that cover sRGB have RGB with comparatively wide
spectrum, though they don’t intersect generally. Good displays have
well-separated RGB leds (I find all of such dispays use the same physical diods
by spectrum).
* In the case where normative RGB pixel spectral curves are real normative for
your working standart profile. This means that DCI-P3 has better coverage of
reds than AdobeRGB and, so, the display red pixel peak will be in deeper red
area or the curve will be wider, meaning more emitting energy.
* When working profile implies linear RGB values transition (like sRGB does).
* When color saturation on display screen is limited to working profile
physical saturation maximum. Here is the problem: how can we do it? Two days
ago I tried to use internal LUT & proprietary calibration tool with LG
pro-graded display, but I still don’t understand how CM application (i.e.
Photoshop) transmits some JPEG with incorporated ICC profile to this display,
how does it do correct profile link for RGB-values to physical color? That
display overdones sRGB significantly, so videocard 255,0,0 output was more red
than that of working sRGB profile. In theory that display should be calibrated
for some one standart ICC profile to work with.
- Any ideas?

if you have a display that has an inherently good tone curve characteristic,
then you are better off setting the white point etc. using the displays
controls
and skipping directly to profiling. There is good logic in this.
