I'm currently in the market for a new TV and the stand out so far from all of my research is the Hisense B8000UW as recently mentioned above. This is purely going on paper and I also cannot confirm if the local version has Android TV compared to the H8F. Tafelberg in Bellville has it in stock, hope to go have a look for myself. But that said you get Dolby Vision support, and if no Android TV present you can get a Dolby Vision supported media player (Apple TV, Chromecast Ultra etc). I just hope the local dimming is as good as the reviews say for the H8F.
The Skyworth Q3 was also on my list but no Optical Out present as I will use it with a Samsung Sound Bar and no Dolby Vision. I've scrapped LG from my list as I prefer the contrast ratio of VA panels compared to IPS. The Samsung Q6FNA from 2018 would be my pick if the main use would be gaming. Can be found on special here and there in the same ball park price range of the Hisense B8000UW.
