I have a Sony XBR-65X930D purchased around January 2017. I recently upgraded to the Arc soundbar.
If I have an Apple TV 4K can I pass through Dolby Digital Plus via the HDMI Arc? As I understand it, it is possible. However, Atmos lossless is not possible because the tv is not supported and there is no eArc.
I ask because I was running some tests and audio seems to only be coming out as Dolby Digital 5.1. I was watching Space Force via Netflix and I would think it would be in Dolby Digital Plus. Are there any changes I need to make on the Apple TV and/or TV?
