I'm pleased to note that all colors are specified in the sRGB color space.
Does TT AF DFXP express any conformance requirement regarding the
fidelity of the colors when converting to and from DFXP? I am thinking
not only of chrominance and white-point adaptation effects - which
should be minimal for modern equipment given that sRGB uses the 709
phosphor chromaticities - but more for differing assumptions on headroom
footroom, allowed colors, and corrections for flare, scene brightness,
surround and other viewing condition effects.
