New iOS tv app

Hi All,
Today a new TV app appeared by itself on my iPhone 6s. It appears to be an app from apple to sync and consolidate all your media. I've played around and it maybe quite good. However, does anyone know if/how you could use this with AD?. I've checked settings and the app itself and I have a feeling that audio description may not be an option. However, I do have AD turned on for my phone so was wondering if it would just automatically play if AD was on a programme. Anyone got a clue?
