I noticed in your ThemeKey that you wrote you do not know how to change the apple logo under f(x). Here's a small bit of info:
The Apple logo image is stored in Assets.car in SystemAppearance.bundle. Think of SystemAppearance (and all the other *Appearance.car files) as being corollary to ArtFile.bin in the old days of theming and Assets.car in SystemAppearance akin to SArtFile.bin.
Note on the f(x): They are encoded CALayer trees which contain information on how to apply GPU-backed filters to UI elements (mostly).
