I have had the 976 for a while. Picked it up when I got a 4K tv. I am just now getting ready to set up a 7.1 system and re-doing other parts of my system and have some questions.

With regards to what is displayed on the front panel for different audio formats:

Will the “DD” be displayed when the incoming audio is Dolby Digital, Dolby Digital Plus, or Dolby TrueHD? In other words, same indicator used for all three formats? Is there some way to see exactly which format is being received?

Similar question, is “dts” being displayed for all three DTS formats?

Regarding the ‘Surround Default’ setting for the various inputs, since the manual only mentions 2 channel input modes, I’m assuming that if you are receiving something like DTS Master Audio (7.1) on that input, then the ‘Surround Default’ is ignored and the 7.1 is passed through. Is this correct? In other words, only a 2-channel (or All-Channel stereo) signal would be converted using the ‘Surround Default’ setting?

Thanks for any input.
