What kind of color formats do you have in mind ?

For panels that support several video modes, sure, we need a way to set the 
video mode. I don't have access to any such panel though, that's why the 
operation has been left out. It wouldn't be difficult to add it when a real 
use case will come up.

What do you mean exactly about HDMI monitors setting EDID ?
