Perhaps I am not understanding your dilemma. The name of the camera will not show in the calibration drop-down. It should show in the title bar of the Camera Raw window. But the calibration drop-down will only display the profiles that are appropriate for your model. You do not have the option of choosing different camera model profiles.
I was at a Kelby Seminar last week and when he opened Camera
Calibration his Canon was listed with different profiles. How'd he do that?
What do you see in the Camera Calibration Dropdown? The only things you should see there are the various profiles for your camera, not the camera-name, itself.
Adobe Labs' DNG Profile Editor can adjust profiles, and both Adobe and X-Rite have a profile-creation solution using an X-Rite color-checker as the calibration target. I carry around and x-rite Passport if I am going to be in a new lighting situation, so I can create a custom profile for it if need be. I have also created general-purpose dual-illuminate profiles for my cameras. If you tweak or create your own profile, you can name it whatever you want, so I suspect that is what Kelby has done.
Those are White-balance choices from the Basic tab, not camera profiles from the Camera Calibration tab, so I'm not sure what this discussion is about, anymore.
Camera Calibration should say things like:
Oops! Sorry about that.
That's what I have, too, for my 300D camera, plus a few more that I've created, so there's nothing wrong with your profiles. If ACR couldn't find the .dcp profile files for your camera it wouldn't list anything other than the two ACR x.x items.
They were probably using additional custom camera profiles at the seminar. Your list is the default.
