I should have made clear that I was aware of this limitation. But what I am
getting at is that even with the VCGT in Photoshop will not display the
white point differently. If my monitor is calibrated for D65 and I display a
ColorMatch image the appearance of R=G=B=255 is the same as if my monitor is
calibrated for D50 or 9300K. Yes, the appearance of R=G=B=255 is different
under the three calibration because, phusically, the monitor will have
different chromaticities for the different target white point. But my
"point" is Photoshop is not managing the white point absolutely. IOW, if I
display a ColorMatch image onto a 9300K calibrated monitor I'd like to have
some indication that this image looks yellowish as opposed to bluish.
Currently, Photoshop is ignoring the image white point altogeher on the way
to the display, it justs maps whathever image white point to whathever
monitor calibrated white point in a relative fashion. And that's what I find
weird. But maybe it's just me ;-)
