vangel76andClaude Opus 5.5 8ac4c9d268 Color: Generic CMYK compensates black both ways so black round-trips (#2493)
sRGB to Generic CMYK applies black-point compensation (black separates to the
darkest rich black) but CMYK to display did not undo it, so hex 000000 became
C67 M67 Y67 K100 and then showed as #1b1818. The display XYZ now maps the press
black to black when the colour settings use black-point compensation, in the
sRGB conversion, the ink lookup table the canvas uses, Lab of a CMYK colour and
the gamut warning.
