As the Argyll CMS does not support V4 profiles yet, I will create new profiles the way you suggest.
Regarding the viewing conditions, is it possible (with LittleCMS) to adapt the color conversion to the ambient light? i.e. if I create a profile for D50 ambient light, could I adapt the color conversion for something different, like incandescent light? And if yes, then is it possible also with V2 profiles? Thank you.
