It does, but I've never managed to get it functioning correctly, just can't get it to connect to Plex media centre.
However, the full Plex library appears on the in-built LG Video/Photo app and all video's stream well, even 4K over Wi-fi, just not as nice an interface as Plex. No HDR from what I remember though.
HDR working great on my 65B7 via the built in DLNA client
If you are quick the 65B7 is currently 1999 at Richersounds! Bargain at that price surely?
