lcms v1 can handle ICC V4.x profiles since quite some years. So most linux 
applications are ready for them. The big new feature in lcms 2 is true 
floating point support and icreased precision.

Provided of course that it has not been edited to Correct The Spelling or whatever other edits were made; there does not seem to be a licence to produce derived versions, even if such derivatives were desirable which is not clearly the case.

The current ICC license requires to not alter the ICC profiles at all. 
However this condition is in conflict with The Open Source Definition 
section 3. Derived Works.

I guess a changed formulation can help to overcom this conflict and 
maintain integrity of published profiles as desired by ICC and other 
vendors.
