  I tired this, but it doesn't seem to work... I set night-light-schedule-from=23.0 (11 PM), and night-light-schedule-to=6.0 (6 AM). I tested at 8PM. My user account's night-light is set for sun-down to sun-up. In my test, I expected GDM to ~not~ have night light active. However, night-light was ~on~ in GDM. It seems as if GDM just follows the default settings (sun-down to sun-up), ignoring the greeter.dconf-defaults file?
