But that's not what image-scaling-factor is about -- it's about scaling
images up on HiDPI screens (to make them visually larger, i.e., the same
size as on a non-HiDPI screen).  So it sounds like this is a roundabout
way of setting image-scaling-factor back to 1?

Uhm...  but on Macos, Emacs doesn't know the physical pixel size, I
think you said earlier?  So...  er...  now I'm confused.  :-)
