right, I didn't mean that the mimicry happens during a 'compressed'
grade, but that it is a general technique in color correction for
obfuscating video's limitations. If you have very little curve to the
signal, you have very little sensation of the relative spacing/number of
the bits available, therefore you're not tipping your hand as to the
inferiority of video (over film). I think this is kind of why the
crush+clip fashion came about in the recent past.

I remember when Encore started doing it, roughly the early 90's, and
now I know of other episodic houses using that technique.
It's better suited for shows I think than for commercials, in general.
