Windows 11 doesn't currently use WinUI 3 at all, it's all still WinUI 2.x/UWP XAML based, including the new stuff.
Actually I don't think WinUI 3 currently has any immediate advantages over WinUI 2.x from the app developer's point of view, except that there's a nice Visual Studio template for creating standalone Win32 apps using it, but I believe you can achieve more or less the same thing with a little more upfront work by just making an app that does its entire UI in one big XAML Island, and in fact that's how Windows Terminal works. The long-term advantages are supposed to come from WinUI 3's XAML and composition stack being decoupled from the Windows OS build.
