Audio Transcoding Behavior on Google TV Streamer 4K

I’m confused about the audio transcoding behavior that happens on the client-side with a Google TV Streamer 4K.

My setup:
Server is direct playing a movie with a DTS-HD MA 5.1 audio track.
Client is a Google TV Streamer 4K, which does not support DTS-HD MA.

With the client-side “Audio Passthrough” option set to HDMI, my AVR receives a DTS signal. My understanding is that this is the “lossy core” of the DTS-HD MA audio track.

With passthrough disabled, my AVR receives a PCM 5.1 signal.

When passthrough is disabled, I am not sure if the Plex client or Android is doing the decoding to PCM, and I am not sure if the input to the decoding is the full DTS-HD MA track or the lossy DTS track.

How can I determine who is doing the decoding and what the source is?

Anyone know the answer here? Does the Plex client on Android TV perform any decoding to PCM?

Anyone able to say how this works? I assume that Plex has not paid for the licenses to decode the lossless audio track, but it’s confusing since the server says that is what is being played.
