iphones are all OLED now, so there is no distinction.

On an old LCD display there are some filters that do a linear/nonlinear mapping from 0->255 brightness to 0->64 for example, leaving the actual backlight at the same brightness. The downside is that colour banding and quantization start to get really bad - and 'black' starts to look very non-black.

My older iphone is not oled so that would explain why I did not like this setting when I tried it some time ago like what you say about blacks looking out of balance. Thanks

The latest iPhone SE still has an LCD screen. It was released in 2022 and is still a current model.
