The photos may be HDR’s and have a dynamic range the display can’t reproduce. If you use a photo you take, what does it look like? If you use a default Wallpaper that Apple provides, what does it look like?

What iOS are you on? Latest version for your iPhone is 18.2.1.

Are you using a stock Wallpaper Apple has provided or a custom background you edited?

What program?

I wasn’t asking about Wallpaper programs. What Wallpaper were you using? Was it a photo or artwork you created?
