I don't think so.  The supported image types do not depend on the
actual display currently in use: they specify what kind of images
Emacs is able to decipher and load.

If you want to know whether they can be _displayed_, use

There is one possible inconsistency I see: postscript images work only
on X displays because they are implemented using X properties and X
Pixmaps.  So their availability is a mixture of the decoding routines
and the actual display type involved.

But for everything else, I don't see an incitement to have image-types
be display-dependent.  B&W bitmap displays should probably _prefer_
monochrome image formats if available, but I don't know if they should
actually fail when only color images are there.  Given current
hardware, we probably don't need to worry too much about that, though.
