I'm don't disagree. I totally understand why. I'm just saying it may affect things and how both Color and FCP expect to receive and interpret the levels. I was also going under the premise that the Avid levels would have been kept between 16 and 235.
My general assessment is that FCP *seems* to work in a range where 16 is mapped to 0 and 255 is mapped to 255, with a corresponding gamma shift in the middle. However, when I've tried to test this, sometimes I get results consistent with this theory and at other times, not.
In any case, Color works differently as well and doesn't match FCP either. AFAIK, its internal processing is RGB with different gamma, hence the same shot in the Color GUI will not match itself inside the FCP GUI. They will only be the same on an SDI output.
