Presumably if you get it working for 15/16-bit then the same algorithm could be used for 24-bit? It's actually not unreasonable to dither 24-bit images. Things like blue skys and the slight artificial gradients used in modern UIs can look ugly because of visible banding. You really notice this sort of thing on slight gradients that are faded to/from black. High-end image processing for video and film is occassionaly done with 16-bits per channel to get around these issues. Though digital video generally drops things back to 8-bit per channel, you can at least add dithering at that step :). Digital cinema uses 12-bits per channel JPEG-2000, not just because hollywood types are ignorant about technology... the banding in gradients (often sky and shadows) would be visible.
