Not sure if this is an iOS 16 thing and if “HDR” would be the right word, but some of the UI is clearly brighter than the other pure whites, which is surely OLED specific, unless Apple is using EDR just for this effect.

Ex. 1: The share sheet has this “HDR” where the list of actions is slightly brighter than the pure white of the AirDrop, Reminders, and Notes icon above it.

Ex. 2: This one is incredibly noticeable, in Mail, the banner “Found in Sent Messages” is super bright which makes the pure white background of the Mail app look grey.

I also tested this with taking a screenshot of the app, and when I view the screenshot in Photos, all the whites are matching.

Interestingly, when I tap the thumbnail after taking a screenshot, the UI still shows the HDR UI, but not in Photos.

When I go to the app switcher, all the whites match. When I open the app from the app switcher, the UI fades in the HDR UI, like an HDR video would.
 
Which iPhone are you using?

In iOS 15.5 the action bar is white while the white in the icons are actually off white. Its a bit of pain for me to grab the colors without crushing the whites but even after I do there is still a measurable difference.

I have many iPhones including the latest Max and mini but I don’t see any difference in UI on iOS 16.

I will have to take a picture of my phone later to show the difference. Taking a screenshot removes the HDR effect from the UI.

This has been the case on my 12 mini on iOS 15 and I've always thought it was a bug

My homescreen icons definitely look sharper on my 13PM. But I wasm't sure if it was because I chose a different background
