What it is

Forces you to login to a Samsung Account if you want to download ANY content (icons, wallpapers, themes, etc.). If you already downloaded something, you can apply it "freely".

Not needed for Wallpaper API, so any app (Samsung or not) can set Home & Lock wallpapers. However, on some devices, this app is required to view/apply built-in wallpapers (in that case, it requires "com.samsung.android.themecenter" service).

Commands

adb shell pm uninstall --user 0 com.samsung.android.themestore

To put it back:

adb shell cmd package install-existing com.samsung.android.themestore

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
