Not sure how many people this affected, but seemingly lots of Google hits out there.
Until the last AMD driver release - and for a number of years in fact - every time the display went to sleep, when it resumed Night Light settings would be ignored. Regardless of whether you used F.lux or Windows Night Light. The only way to fix was the Shift-Ctrl-Win-B driver reset hotkey.
It was always an AMD specific problem and despite a lot of bug submissions the problem was largely ignored.
In fact in the interim I began to wonder if my Dell monitor had developed a fault, or if I should buy a new DP cable (despite this one being VESA certified). I'd already changed the cable once.
Anyway, long story short, after the last major Radeon software update (a couple weeks back) the issue has been fixed. Hurrah! Two years or so of that bug and it turned out to be an AMD driver issue after all.
I guess I should thank them for belatedly fixing it.

Well done, AMD.
