Just switched from fire cube to Apple tv 4k. I am not getting Dolby Atmos display on my JBL 1300x Soundbar. Just displays Dolby surround.
On all apps including Apple tv+ , Netflix or Amazon Prime.
If I put in a DVD, it displays Dolby Atmos .
Apple TV 4K, tvOS 18
The Apple TV box outputs Dolby Atmos in Dolby MAT format, which requires eARC between the TV and the soundbar. Regular ARC doesn’t have the needed bandwidth for that format. Could it be that the TV doesn’t have eARC, or isn’t configured for eARC?
Is your setup done like
Apple TV →[HDMI]→ TV →[HDMI (e)ARC]→ soundbar
or like
Apple TV →[HDMI]→ soundbar ⇄[HDMI (e)ARC]⇄ TV
Either setup is functional and fine, unless one puts limitations on what works, e.g. from port specifications.
If I put in a DVD, it displays Dolby Atmos.
Blu-ray discs may have Dolby Atmos, but Dolby Atmos is not part of the DVD-Video specification. DVD supports Dolby Digital, MPEG-1 audio, PCM audio, or DTS.

TY
That helped alot. On Fire Cube, worked best if plugged into tv. Apple works better if plugged into Soundbar :)
I haven't experienced the same issue but perhaps this article will help: Set up Dolby Atmos or surround sound on Apple TV with a sound bar or AV receiver - Apple Support
