This is probably the cause and solution. Profiles are applied in-camera for JPEG, but typically only for the same lens brand as the camera. Also, you have enable these profiles to be applied. And for EOS cameras, you may even have to download the profiles from Canon and install to the camera. When I said I has page(s) of Tamron, I had opened a Sony RAW file in LR6. Profiles are not applied to RAW files, just the EXIF data of the lens used and various shooting settings.
Problem solved. I don't know how or when the setting was switched to JPEG but it is now back on RAW where it's supposed to be.
