I saw a DP 1.3 panel that advertise AUX backlight brightness control

I think that is good reason enough to add this as a heuristic.
Either key it on eDP 1.4 and hope that it's a reasonable expectation,
or employ a whitelist (potentially lots of effort adding all displays that
supports AUX backlight, but safe from regressions) or a blacklist
(potentially fewer displays need to be added, but risks introducing
regressions for end users).
Kind regards, David
