I think the black is too depressing, and I knew a few printers who did it, because they admittedly had some problems with printing good highlights, and they hoped to overcome it with a black mount. They are right, it does help with the highlights, but they are paying for it with weak blacks in the print. Once they learned to print the highlights, they dropped the black mount.

Having said that, one function of the mount is to isolate the print from its surroundings. Depending on the wall color, black may work well.
