Oh, I quite agree. And, while I see differences in other cameras, I think there’s reason to believe that most cameras data can be manipulated to produce consistent colors. When a camera profile is built against a color target, the objective is to come up with a set of primaries that pull the respective camera recording of a patch as close to the XYZ reference for that patch as is possible. I see manifestation of that behavior in the reporting spewed by dcamprof for every profile I’ve created with that software.
