I don't think typically they'll be many different profiles in use, on a typical system most things will just be (assumed) sRGB to 'n' display profiles, where n is the number of outputs. > Is that a reasonable requirement for all compositors that support > per-output ICC profiles? I think it's a very little amount of work, IMO doing it centrally makes a lot of sense as some bits are tricky to do correctly. Overall, I'm very happy to see someone pick up this work. Thanks.
