Agreed if its not shared, it can obtain a different namespace. This
sounds already like the end of brainstorming.

"soft" is not ranked after "hard", its just put in an other list. Hmm

For profiles profilers get used. So a "calib" value is pretty ambiguous.
Would the calibrator for any display profile on Linux be VCGT or maybe Xorg?

I refered to DATA_ being not bound to any standard or something. EDID_
is clearly referring to a standard. But you might have not intended to
use a namespace here.

np. I can rename that to an other prefix as well.

lcms puts its signature into the profile header already, because it is
the profile generator.

The following keys names would make sense to me. They are close to what
you proposed.
OPENICC_profile_origin
OPENICC_profile_binary
OPENICC_profile_binary_version
