My dear jyqvklioo (do you work for a throat sweets manufacturer btw? :-)),

I have a suspicion that you are confusing back-end with
implementation. If Krita passes everything through sRGB, then it is
because either it doesn't allow specifying a different working color
space or it does allow that, but you didn't do it. LittleCMS has
nothing to do with that.

However feel free to prove me wrong and quote the bit from LittleCMS's
docs that explicitly confirms your opinion.
