Really? Oh goody! The Acorn does the same and it has been driving me nuts trying  to work out how to deal with it properly. I guess the difference that gets you out of trouble on w95 is the ability to specify the palette even for 16/32bpp
 displays. On the Acorn some nitwit decided that palettes were not need since 'obviously' it was a true rgb format..... grrr.
When I was doing the little endian bitblt I nearly went for making the changes to reverse the rgb order but stopped because it looked like the pc used same format as mac and I couldn't see wasting the time for only the one platform. Now i
f it turns out that pcs need both little endian _and_ reversed rgb, maybe it would be worth it. There is potential for some useful performance improvements.
