That's a viable approach, but leaves the user with a rather
non-intuitive means of choosing settings - they have to
search for a profile that has settings they want, and
choose it.
A more flexible approach allows the user to specify any setting
they want, and finds a best matching profile to suite. You can
finesse this with something to indicate the degree of fit, and
ability to then load the settings from the profile for a perfect
match. They may not want a perfect match, they may just want
the best color that can be managed with those settings.

Dynamic PPDs are a halfway house to this, but a really good UI
needs two way information from the driver & device - how else
can you communicate the current state of a device to the user ?
