NVIDIA SHIELD Android TV Pro to go with Dolby Atmos Soundbar

[TestLink]

I am thinking about buying a NVIDIA SHIELD Android TV Pro to go with Dolby Atmos Soundbar. Saw the below on Amazon.​

https://www.amazon.co.uk/NVIDIA-Shield-Streaming-Player-separately/dp/B07Z6RD4M9 or
https://www.amazon.co.uk/NVIDIA-SHIELD-Android-Streaming-Performance/dp/B07YP9FBMM

1. May I know what is the difference betweenn the above two ?

2. Would I be able to install all Google Playstore apps on the above?

3. I wont be playing any games using the device, but watching 4K movies with Dolby Atmos and also streaming content like IPTV. Is there any other cheaper choice for me?

4. Would it be better to upgrade my TV to a Dilby Atmos + Dolby Vision model rather than buying an Android TV Box like NVIDIA SHIELD PRO?

Thanks...

No, so long as the player itself supports Atmos (and assuming the soure data includes Atmos coding). Of course if the Atmos data is not in the original data, just writing it to a BlueRay won't add it.
