@tdaede @phastphill @shawn-singh,

Could you clarify what the playback layout is for this case? Mono or Stereo

Here are my understandings.

If the playback layout is Mono, then I think that it is out of scope and implementation issue.
If the playback layout is Stereo, then Mono should be rendered to Stereo according to our spec. When the Stereo is playbacked through stereo speakers, devices would do loudness normalization by referring the loudness info for stereo layout in Mix Presentation.

Please refer to 7.3.2.1
