I recently bought a 65" 4K HDR tv. It certainly has that wow factor, especially with GT Sport. However I still drive better on my 1080p projector at 92", screen size matters more than resolution at 1080p and beyond.
The wow factor of 4K didn't last as long as I expected, but HDR still does it. Most of my movie / netflix watching and racing will still be on the projector though, other gaming on PSVR. The 4K tv looks great in the living room, big upgrade from my premium 1080p tv from 2007.
