Yeah, the SE will have zero issues with PWM being LCD. I've never had issues with temporal dithering that I know of, but I know some people don't get along well with the XR/11 screens. My XR screen has always been great and easy to look at for long periods of time so, thankfully, I think I'm only sensitive to PWM flicker. I don't even notice the dreaded jelly scrolling on the iPad Mini. If someone hadn't told me about it and exactly what to look for, I wouldn't have noticed. Funny how reviewers made jelly scrolling out to be the end of the world, but this PWM thing just get totally ignored.
Thanks for the response!
You mentioned temporal dithering on the xr/11- I assume that means the SE has it as well?
