Some idees about different user needs:

The average user only wants a button to select enable/disable use of the
default profile and the default settings belonging to the profile.
After that the user can use for example Gimp to check/change the scan.

Default profile generated by the manufacturer or backend maintainer(or
any body else who supplied a profile file with a settings file).

The more demanding user wants to select between different profiles
depending on his scanning object.

The advanced user wants to add his own profiles to the backend and use
them when he wants and takes the effort to get a reference target and
use it.
