No Dolby Digital 5.1 on Apple TV 4k(Gen1 and Gen 3)

I recently noticed that my Apple Tv 4k Generation 1 and Apple Tv 4k Generation 3, no longer displays Dolby Digital 5.1 but as PCM 5.1 for any content that has 5.1 audio. This is happening on all streaming apps(Netflix, Prime, HBO, Hulu, and etc).

There are no issues with content with Dolby Atmos. Both my receivers will display Dolby Atmos from both Apple TV 4k.

Is anyone seeing the same issues? This wasn't the case few months ago

It should be, as Apple TV has long time been programmed to use decoding to PCM Multichannel for the ‘Auto’ (best quality) audio format setting. It works as intended. Adjust other audio settings - Apple TV user guide - Apple Support
