I don't understand what this means. I still think you are getting
the data and the *display* of the data mixed up.

TV doesn't do anything but light up pixels on a display according
to information you supply it. It's a lot dumber than you give it
credit for, but maybe that's a good thing.

Hard to say. If I didn't know Kelly better I would have
sworn he was hitting the sauce early today. But, I'm curious,
too.

No, just 8 bit color tables. 16 and 24 bit image arrays
have their colors built in. There is no need for color
lookup tables. (There is nothing to "look up", the color
is there staring you in the face.)
