The lcms profiles collection provides some Rec.601 and Rec.709 YCbCr
to LAB profiles. These have a whitepoint of D50 while Rec.601 and
Rec.709 use D65 as their native whitepoint.
Can these existing profiles be used to perform a proper conversion
from Rec.601/Rec.709 YCbCr to RGB (e.g. sRGB) even though they are
claimed D50 rather than D65?
Do any profiles exist for Rec.601/Rec.709 which are for the equivalent
RGB rather than YCbCr? What is necessary in order to create such a
profile?
