My Hisense H49M3000 supports 10bit HDR from my PS4 pro (although I believe the panel is 8bit and 10bit HDR is implemented through emulation) for £350 I can't fault the quality of the TV. I'm particularly impressed with how up scaled content appears, even the text in the virgin tivo menus looks sharp. Obviously stuff like ratchet and clank look a fair deal better.
Some extras I was attracted to.
Dual tuner (One Freeview One Freesat)
Passable smart TV support (Netflix/Amazon/Youtube/Plex) Note:not all have 4K support.
HDMI 2.0 with HDCP 2.2 4k@60hz/HDR support (on 2 ports only, with 2 additional hdmi 1.4 ports)
1 USB 3.0 port and 2 USB 2.0 ports (so far the USB3.0 only appears to support a 32GB drive so it's functionally useless in my opinion, the others are handy for chromecast/firestick power)
1Gbe Wired socket
And lastly a headphone socket (without which is a dealbreaker on other sets)
Frankly at £350 for a 49" I couldn't see anything even 4K from other manufacturers.
Good luck what ever you buy.
