Greetings!
Currently I am running Kodi in Windows 10 env with Vega64 +Ryzen2700x, but I am looking for an android box or similar (some s912 EC or Zidoo z9) becasue hdr is a mess on windows and there is no auto res switch by default (I want the lg c8 to scale up).
Assuming very high bitrate top remux sources:
- will be the picture quality the same?
- will I lose something?
Do you guys have any experience with that?

Considering you have a Vega64 and Windows 10 have you considered Kodi DSplayer w/madvr?   Nothing will touch madvr when it comes to upscaling to 4k.

You could also use Kodi with an external player that uses madvr.    Unless something changed for the 2018 LGs there's nothing special about their upscaler.   Sure its better than a Nvidia shield and cheap boxes - not so sure it's better than a PC and definitely not one running madvr.
