Kinda, kinda not. 4K is pretty much the limit for a normal viewing angle. Go closer and you'll notice the difference. It has however reached the point of diminishing returns though.

Money is much better spent on other parts of the viewing, like HDR or better pixel technology (OLED etc) and increasing dimming zones.

maybe higher bit depth and 300+ refresh rates at 4k will push for a new standard
