mmmmmm. Not quite. As far as I have read on Flame news the problem stems
more from DL inputing "correctly" (thats a different debate) limited
0-100 units 4:2:2, expanding it to fill the extra 16 available levels
above white and below black, then chopping it off again after
processing, thus causing color shifts.
The only way to control the situation seems to be to make sure you stay
within "gamut" - this at least minimises the problem.
