the sane protocol is designed such that you could layer 'meta'
backends between the real backend and the front-end. I suppose you
could write such a meta backend, add a new frametype for ICC data, and
have the meta backend return the profile as an 'image'. But, that
seems like a bit of a stretch of the API, and there is also not a good
way for your meta backend to dynamically squeeze itself into the
"The truth is an offense, but not a sin"
