Does not output Dolby Atmos from supported apps
I am from India. recently Purchased Apple TV. I am having issues in installed apps - ZEE5, Sony-Liv, aha, Prime-video etc. My device does not output Dolby Atmos from supported apps and the content in it. The same sites, I am using in my Sony TV gives full support with Dolby Atmos and 4K. Instead TV+, iTunes, and Netfilx gives the appropriate Audio and Video. Is there any solution for this?
Device setup: Ethernet-150mbps, Video Audio setup - 4k Dolby Vision & Atmos.
Connected Style: AppleTV - Audio quest Cinnamon 48 HDmi cable - Marantz SR7015 - Audio quest Cinnamon 48 HDmi cable - Sony Bravia 55X9000F
Thanks in Advance
Apple TV 4K, tvOS 16
