iOS 26.1 wallpapers lose saturation when changing or switching to dark mode

Why do IOS 26.1 wallpapers lose saturation when I change them (also when iPhone switches to dark morde and vice versa)? It’s like all the colors fade and if I restart the phone everything goes back to normal. Same thing for the dark mode
