Edit: I am one of the few that is affected by certain screens and certain devices flicker in whatever way they do it be it PWM or dithering or unknown, others are likely different but reduce white point helps me.
Yes, it likely wont affect any dithering etc but if you're affected by 'both' it can help as the brightness is quite bright, its hard for me to describe I perceive it as the colors are too bright even on the dimmest setting, however reduce white point makes the colors less intensive and easier on my eyes.
Personally I believe the CPU/GPU on the Iphone 8 / 8+ and older do not do any dithering / as much dithering but iphones from the XR onwards DO. (I say dithering but whatever it is doing that also casuses the migraine)
(but then again who's to say the screens are not different as well)
However the iphone SE2 is essentially an Iphone 8 with the insides of an Iphone 11 and it is not usable by myself as I believe the A13 chip is doing dithering / SOMETHING that causes me migraine when using, even on lowest brightness setting with reduce white point and other acessibility options it is not usable by myself.
Another thought I had, say dithering is essentially flickering /flashing a pixel color to simulate / trick the eyes/brain into seeing a different color, if this was very bright flashing would it be worse than if it was much dimmer but still flashing?
