If the aim is an integrated color sub-system, then it would seem appropriate
that there should be a single database location for devices that are
managed from a particular system. (The Elektra database has
been suggested, and it is a system wide configuration database).

Why ? X11 Clients will get the default installed monitor profiles from the
_ICC_PROFILE atoms.
It's the system that is managing the X11 server that needs access to
a database of monitor to profile associations, plus the profile itself.
(Interestingly, I don't think that the system managing the X11 server
necessarily has to be the same system running the X11 server.)
