I've implemented a Transform Cache in PhotoPrint - I think I've
mentioned before that as a "signature" for matching the correct
transform I use an MD5 hash of both source and destination profiles
(excluding headers), as well as the rendering intent. Just throwing
that in, in the hope it might be useful.
