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.

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...

There is no difference except the price.
The cheaper one is sold by Amazon the best option.
The dearer one is sold by a third party.
