Hello together

Maybe someone can help me.

I am using the LG OLED65CX, the Nvidia shield pro and the Sonos Arc with 2 ONE SL as rearspeakers.
I used the HDMI cable supplied by Sonos as the connection from the TV (HDMI eARC) to the Sonos Arc.

I also adjusted the following in the TV settings:
HDMI eARC -- on
Audio output -- HDMI ARC
Digital audio output -- pass through
Adjust AV Sync -- Bypass

Now when I start playing movies from Netflix or Disney+, which according to the info have DolbyVision format, the Sonos app shows me Dolby Digital Plus 5.1.
However, as far as I know, this is not the full Dolby Atmos (but compressed). Or am I wrong here?

By the way, it doesn't matter whether I stream it from the Shield or directly from the TV.

Can you tell me if I need to adjust anything else or if I am fundamentally misunderstanding or doing something wrong?

Thanks for your help.

Greetings
