My lcms.c high bit depth profile conversion code still some major issues to iron out, including: *I haven't rewritten to use nondeprecated functions the code section that takes care of alpha channels. *The show-stopper: the code still doesn't work correctly at high bit depths unless some/all of the Babl functions that convert back and forth between the sRGB TRC and linear gamma TRC are modified to stop the back-and-forth conversion. Otherwise, as I've noted before, tonality AND color are wrong after the profile conversion. Unfortunately, replacing the deprecated functions didn't fix this problem. The problem seems to be that when doing an ICC profile conversion on an image with a bit-depth greater than 8 bits, a couple of functions in babl/base/model-rgb.c are called midway through the ICC profile conversion. These functions are not called when converting an 8-bit image. I haven't been able to track down what bit of Gimp/Babl code calls the functions in model-rgb.c while the ICC profile conversion is in progress.
