Full disclosure: I work for Roku.
I have 3 55inch flat screen tvs.
The one in my studio is a 5 year old LG 1080p 3D TV. (Oldest of the bunch) it cost me $2,500 new and I’ve been happy with it for 5 years as a gaming TV.
In my bedroom is an Insignia 4k Roku TV (without HDR) that I purchased last year from Best Buy on sale for $430.
In my living room is this years Sharp 4k Roku TV with HDR that retails for around $800 when not on sale.
Plugged into it I have an Xbox One X Scorpio edition and a standard PS4.
For PS3 3D content (pinball Arcade mainly) I still like my 5 year old LG. The display lag is about 23-32ms with all the special features turned off. Color is pretty good for the most part but it loses a lot of detail in bright and dark scenes.
The tv in the bedroom is ok. It’s 4k and the color is alright but high contrast scenes have an obviously visible gradient. I haven’t gamed on this tv
The one in the living room blows my mind. The colors are dead on to me and the detail in bright and dark scenes (especially with HDR content) has to be seen to be believed.
Playing X1X on this thing I finally feel like next gen gaming has arrived. Ironically the first game to make me feel this way was the X1X enhanced Mirrors Edge from the 360 played through backward compatibility. The buildings are razor sharp and the HDR is very impressive in game.
The display lag is somewhere between 10-15ms which is the lowest I’ve ever had in a flat screen tv of this size.
Most Netflix originals are now available in 4k many with HDR. The difference is huge. Amazing Prime Video originals are also in 4k HDR now.
Vudu now supports 4K HDR and Dolby Vision content.
Things have advanced a lot in just 5 years. A good 4k TV with HDR can make a huge difference and doesn’t have to break the bank.
Checkout the Sharp or the TCL P series of Roku tvs this year and keep your eyes out for sales.
Here is a Best Buy link to the 55 inch TCL p series:

Here is the avsforums assessment calling it one of the best tvs currently available for gaming so you don’t have to take my word for it:
