see you use a lot of black wallpapers you could try hide doc and status bar above you need iOS 15.2
Most of the home screen wallpapers I use hide the dock.
What about the status bar?
Led this looks great Do you have this wallpaper for the 13 mini? If you do, can you please share. Thanks!
The home screen will only fit the 12 Pro Max. The lock screen you might can adjust or edit to fit.
