I guess it exists a similar problem with 16 color images?
They are identified as 8-bit PseudoClassRGB.

A IM will read in the image before identifying it and it does not use
24 bit values, IM probably will not be able to tell you.
You will need a specific BMP identification program, such as provided
for other formats. EG: jpegtrans pngtrans giftrans
I don't know what you can use, but maybe the UNIX file comannds
can tell you.
