I don't have a breakdown on this, but I know many monitor spaces these
days are gray balanced because the calibration process is assumed to
have gray balanced the monitor. This is not a good assumption to make,
in my opinion, except for the Sony Artisan and possibly the Barco
displays as well. Because of the limitation of using the video card to
gray balance, I think it would actually give us better results to have
color management compensate for the lack of gray balance in a display
rather than trying to force the issue with limited bits in a video
card. Especially for LCD displays.
Either way, it's a fair point that monitor spaces aren't ideal working
spaces because you cannot rely on a major advantage of RGB color
correction, which is that R=G=B.
I'd like to know what apps are creating display profiles that do not
assume the display is gray balanced. Any volunteers?
(2) If you embed your monitor space and share the file with someone
else, a
color space conversion will be necessary.
Someone else using Photoshop can preserve the embedded profile, and
they will still see the image correctly on their screen, and can still
print it correctly as well, using appropriate output profiles. There
may be reasons to convert, but it's not necessary.
