[Openicc] shared-color-profiles issues [was: new/old ICC profile package]

How did the sRGB profile become public domain?
The iCC seems to think it's copyright and licensed
by them with a BSD-like license.

I wasn't aware that ICC has approved 5 different sRGB
profiles (actually 3 different with 2 deprecated names).
I wonder which one we mean by the PNG sRGB chunk?  I
guess the v2 without black-point.
