> you don't have a colourblind person's 'profile'

Why not? As far as my understanding of color blindness goes, you just need to find a precise transformation matrix and offsets to be able to correct any type of deficiency (except for achromatopsia, I guess).

I think the correction applied to digital content is a positive thing. At once you can perceive color the way it was intended to be perceived. May be wrong here because I don't have daltonism.

My goal is not cover every case, but to create exactly one profile (and perhaps create a usable correction workflow for someone else)

Thanks for an elaborate response :)
