The point is on my max and my desktop monitors the first two pictures look nearly the same. You played with the brightness/gamma in the 4th picture to make the picture way to bright, in a way where you are blowing out highlights. You didn't post the specific ios version however, apple supposedly ratched down the processing in later ios releases.Seems like my careful attempt to preempt that objection was lost on you.
"The big difference is that the SE's noise is relatively uniform and not that noticeable under normal viewing conditions. The XR, on the other hand, is somehow managing to make it into huge, ugly chunks that do become noticeable on normal sized displays."
And how do you suppose I noticed this in the first place? If it hadn't been visible in normal viewing, I would have had no occasion to "pixel peep".
The Xs max with a supposedly calibrated oled screen doesn’t show much of a difference in the sweaters. Blowing out the highlights will accentuate the bad qualities. Anyway that’s my take on it.The first two aren't even remotely close. If you can't see it, it'll be because of your monitors and/or viewing environment. I said I deliberately blew out the second two to make it clear what I'm referring to, so I'm not sure what your point is there. Both phones were on the latest version of iOS.
Too much noise reduction on the XR.
I don't care for the JPEG processing performed by my XS Max so I always shoot in RAW, using the Halide camera app. I post-process with Lightroom, just as I do with my DSLR.
I do not take phone photography too seriously........
