it can't save more than 24/32 bits per pixel

Oops, I always thought that only classic is limited to 32 bits. Are you planning to support up to 64 bits per pixel in MP or even classic?

It is not that I really "need" it on my 2011 laptop, but there is a general trend to offer more bits per pixel, and to use some linear transformations instead of convoluted gamma and/or color profile tricks trying to squeeze more than 256 plausible values per channel into only 8 bits. Even BMP can now do 3*10 bits RGB + 2 bits alpha for RGBA.
