Beta 3 dropped still no UI changes whatsoever besides color themes which could have been done with good lock overall not impressed. Notifications still look the same quick toggles look the same. Not hint of material you design at all as far as icons, animations. I'm this š¤ close to ordering the pixel 6 pro if nothing else changes before final release
The Pixel UI (Material You) isn't actually a part of aosp yet I believe. The dynamic theming and all the features was not pushed to aosp yet but I heard Google will push that later in the future. So technically that UI is still not open sourced so other OEM can not implement fully yet.
