Its *.icm, I found now 3.

So, the lcms created profiles are in fact not from Argyll. You just 
claim the colorimetric oinformation is from there. The 3 original 
Argyll ones are no more identical to the packaged ones.

Now I checked, and the profiles in the Oyranos folder are modified as 
well. Please do not refere to them as from the Oyranos project. They are 
not. Most software will handle these profile sets as different. So they 
are technical not the same.

The file mentions just 3 profiles. But there are more.

There is the extension of GPL over derived work.

You can search the OpenICC list for discussions about that topic.

The other way around. I can only require that Oyranos does not ask its 
users to accidentially install the shared-color-profiles package until its 
clean.


These profiles have uncertain sources and are altered without notion, 
they are not a solid reference for compositing and exchange.
