GIMP 2.9.1 (current experimental builds) handle 16/32 bit images just
fine. Feel free to download from my website as it comes with UFRaw
In any case, you have not provided the RAW CR2 file and so it's hard
to see what is happening here. When you say that your CR2 image is
"tack" sharp, you are probably using Canon supplied RAW decoder which
probably is applying it's version of "Picture Controls" prior to
displaying your image.
Hope this helps.
