When VoiceOver is enabled on tvOS or iOS, is there an API to query which navigation mode is currently selected? (i.e.: containers, headings, landmarks, etc.).

Under iOS 13, it's currently not possible.
Even if you can add a new rotor option thanks to the UIAccessibilityCustomRotor since iOS 10, there's definitely no way to get the selected mode information from the rotor.
