The App Store moved the clusters of icons to the home screen, but the messages and wallet app are right next to each other, and tightly integrated. You get to re-arrange and hide most icons, at least.

The UI looks different (information density etc.) but in the end it's still a collection of external applications neatly wrapped inside a platform with strong walls and a strict gatekeeper, with a basic suite available by default. In China, you could ditch most of iOS if you could trick a phone into launching directly into WeChat.
