You can get information about an icc profile with exiftool.
To date I’ve only seen 4 types of icc profiles, but there may be more out there:
- input: those are meant to be used with those devices built to capture real subjects and convert them into images (cameras, scanners, …)
- display: these are the profiles used to show those images in a specific device (usually displays)
- color space: although I’ve only seen them once, they are meant to be used as working profiles
- output: these profiles are meant to convert image data into something meaningful for output devices (typically printers)
As stated in Rawpedia, the profiles used for printing must be of type output device, otherwise they won’t show in the preferences dropdown combo box (and as I said, those profiles must be in the folder set in the directory containing color profiles, and not in any of its subfolders)
