TrueColor uses an immutable colormap (it can't be changed).

With DirectColor each of the red, green and blue channels has a separate
color table which can be modified.  In the case of a 24-bit/pixel visual
there would be three 8-bit (256-entry) color tables.  Per-channel gamma
correction can be done with a DirectColor visual, for example.

In principle, yes, but that's rare.

Sure. You could do that with glXChooseVisual.  You'll naturally get
a caveat-ed visual if that's all that's available.
