I have an LG C3 and that thing is amazing; the issue with HDR/Dolby Vision/etc is not because LG, but rather that you need a system that has an app that supports those capabilities, like if you have a subscription to Apple TV and don’t wanna connect your TV to the internet you need an Nvidia Shield/Apple TV/PS5/Xbox series X because just a HTPC won’t do it because the web browsing app doesn’t offers HDR and the Apple TV Windows app is trash
