CLUT question

1
I am trying to design an experiment using PT where high color images would be displayed full screen. Why is it not possible to define more than 256 colors in the CLUT using the screen function? I understand that most monitors are 8 bit, but from what I understad 24 bit graphics isn't uncommon. I would appreciate it if somebody could explain this to me or suggest a way to display high color images using the screen (or a similiar) function.
