You're right with the first and third things, and wrong with the second and last.
Yes, if you set bitstream, the AVR does the decoding, so it shows you what format and just looks neat while doing it.
But if the player does the decoding and sends it PCM, the decoded stream is not actually "different"... it just displays differently on the AVR since it no longer matters what codec was
used, once "unzipped" it's just multi-channel audio, so that's what the AVR displays. No matter which device decodes the audio stream, the end audio stream should be the same.
But people like seeing those "TrueHD" and "DTS-MA" lights, cuz they're cool, and that ability is one reason why we buy nice AVRs, so may as well show it off. The sound should be no different.*
(* the one exception would be the occasional and rare disc with a stream that one device or the other has trouble decoding... unless there is actual damage to the disc, sometimes switching methods for that one disc can help save the day)
