As Lars said, I've been writing EXR files with ICC profiles from After Effects
and Photoshop for some time. Code for the custom attribute is here:
https://github.com/fnordware/openexrAE/blob/master/src/OpenEXR_iccProfileAttribute.h
My rationale is simple: I can't prevent users from putting non-linear pixels
into an EXR file. The color information I get from these programs is an ICC
profile, so that's the metadata I store. (I also do my best to convert the ICC
info to EXR standard attributes like chroaticity.)
