mobileprovision is another hint, if its not none of them, most likely is sideloaded.

On Android, you can check packageManager.getInstallerPackageName(packageName), its null if its side loaded, or its the name of the installer (store).
Its not possible to know at runtime if the Android app is installed for internal testing only since its the same binary.
Here is the list of installer names https://github.com/ravitejaavv/store_checker/blob/feca50e3168763828e7aa024bb0b3c40b9ce42ab/lib/store_checker.dart#L31-L69
