Dolby Atmos with Arc, HDFury Arcana & Oppo UDP-203

Here is my issue: I am unable to get Dolby Atmos to display in the Sonos app when playing a movie. Here is my setup: Samsung UN55JS8500 UHD TV, Oppo UDP-203, HDFury Arcana & Arc. I have the HDMI ARC Input of the TV going into the HDMI Output of the Arcana. I have the eARC Output of the Arcana plugged into the Arc. The Oppo is plugged into the HDMI Input of the Arcana. When I play a movie that should have a Dolby Atmos soundtrack, my Sonos app displays Dolby Digital 5.1. The movie is being played from a backup of the actual UHD Blu-ray via my Synology DS920+. Any ideas on what the issue might be?

Do actual Blu-ray discs with Dolby TrueHD and Dolby Atmos audio play the correct audio from the Oppo?

How did you acquire the original.

If you ripped it from a retail disc (which is illegal; but that’s not relevant) the Dolby Atmos track was probably prevented from being ripped. Thus you only have DD5.1. The DRM for DD5.1 has long been circumvented.

If you acquired a digital copy; the DRM will most likely not allow a full backup from the source it was originally downloaded to. That’s in order to prevent illegal (there’s that word again) full transfers to external sources such as a backup disc.
