I am running LR CC 2015.8, running on Mac OS 10.12, in the develop profile I only have the Camera Calibration adobe standard profile, missing adobe landscape and all other profiles. I have had this problem for a while but have upgraded to latest version but problem still persists. I am using RAW files from the Panasonic G7 Camera.
Looking at others who have asked on this forum here is some additional information:
In the ~/Library/Application Support/Adobe/CameraRaw/CameraProfiles directory I have the following directories and files
Adobe Standard directory
AS far as I know, there are no camera calibration profiles for Panasonic cameras.
For many of the camera brands, Adobe Standard is the only profile that is provided.
