I think it's going to look alright on iOS/iPadOS where apps are inherently full-screen and the "background images" are really "foreground content" where you do kind of want the controls to "recede".

On the other hand, I can already tell I'm going to despise this on macOS. I always work with windows maximized on my laptop, because I just want to concentrate on the document I'm editing, or code I'm writing, and have maximum space for that. And the past couple of versions of macOS by default make your menu bar a weird pale purple or pink or green that is hugely distracting because it's a blurred image of your desktop. Fortunately you can turn that off with the "Reduce Transparency" accessibility option, which I do.

But the idea that people using Macs want to always being seeing some colorful desktop image around the edges and at the top just seems bizarre to me. iPhones and iPads are more for consuming, so this makes more sense. And within apps on Macs this seems like it'll be fine. But I hate that it doesn't seem designed to let me "tune out" the desktop image while I use an app. It's taking existing translucency and just making it worse...
