Honestly? It lacks the visual contrast that made skeuomorphism so popular. Material You gets this right by using accent colors to break up the uniform interface. It feels cohesive and well-made without feeling clinical or hard-to-read.

It's also, somewhat curiously, not neumorphism. All the interface layers appear distinct, which makes me worry if things like Dynamic Island and Control Center will be mistaken for app controls and not distinct phone controls.
