Not if you are connecting the BD player to the receiver and then passing just the video on to your TV, which is how you should be connecting things.What if I stream through my Blu-ray player ? Would I need the ARC feature ?
The HD with NetFlix, Prime and so on, is video only, not audio, which is Dolby Digital quality, not HD like you get on Blu-Ray discs.
It's DD quality Atmos, which is not the same as HD audio. The Atmos on Blu-Ray discs is HD quality, which is better than DD. Two different things.If that is the case, then it is odd that my receiver shows ATMOS when Netflix advertises a flick with an ATMOS track and DD+ for materials without any ATMOS designation.
Disney+ shows as only DD.
The above is all over the ARC connection.
