First post, so please be kind :)

I have looked everywhere and can't find the answer to this in Apple's documentation or on any of the YouTube videos I've watched (unfortunately I'm not finding the comments/questions feature enabled on the vids that talk about LUFs).

If you mix to Dolby Atmos, I understand that the loudness meter shows the momentary, short-term, and integrated signal levels of incoming audio material. When mastering music for Dolby Atmos, Apple Music has the requirement of no more than -16 LUFS. Which meter are they referring to that must not go over -16 LUFS: only the integrated signal level or are they saying that none of the 3 must go over -16 LUFS?
