I think the tests were written this way because we did not find any driver that exposed this format, and we had a lot of cases in other areas where exposing additional features broke games.

There are also potential issues because X1R5G5B5 is a 16 bit format, just like R5G6B5, which makes depth<->format mapping tricky. If the current setup uses a color depth of 16 bits and the app does not request a specific adapter format, which one does the driver choose?
