Okay, I was apparently way too tired to understand what you were saying last night ;D.

By chance, I happen to have gotten my own PW1 back just today, so I can at least confirm that on 5.6.1.1, nightmode behaves as well as can be.

Which leads me to my next question: which FW version are you running, is this a SO device, and when you say "cover", am I right to assume you meant a smart cover?

(Un)fortunately, my own PW1 is SO, so screensaver handling is honored by the OS, which means there is indeed a race between the system and us, one we mostly always win, so I do get that double-refresh, and the system one will obviously never be using nightmode on a PW1.

There's not much I can do about that without impairing functionality.

This should squarely be an SO-specific quirk, though.

I don't have a cover on any of my devices, but I don't *think* it should affect this.

TL;DR: My money would be on Special Offers.

(On the upside, that allowed me to confirm that SO handling is still working as intended 5 years after the last time I tested it, so, yay).
