Hi,
The both manifest of web and TV client should be same.
We can get to download the 4K video and Atmos audio quality now.
But for the audio stream, there is a difference rather than the other services.
The EAC3 Atmos audio quality is in the H265/4K MPD manifest files, but there is bug in StreamFab, maybe you can download the EAC3 audio quality only when trying to download the H264 video quality.
Anyway, please tell me the video title, so I can check it.
