Isn't it a nice touch?
It's a black wallpaper that hides Dock, folders and the buttons on Lock Screen, and it also hides the bezel and notch!
But only half of each!

It looks like this on the Home button model. I'm sorry, but it doesn't make any sense if it's a white panel.
The dark gray hides Dock and folders, but unfortunately the pitch-black bezel and notch are visible.
However, the black wallpaper can't hide Dock and folders.
Can only one of them be hidden? No, if we give up half of it, we can hide the whole half of it.
