We have a long way to go. 
Never had a fancy TV or monitor. I have always considered contrast ratios, wide gamut and HDR speak to be mostly marketing material. E.g. claimed contrast ratios are often dynamic, not absolute, certainly not per pixel. When you add gamut into the equation, if you wanted to display a series of haldcluts at varying brightnesses spread throughout the screen, how many displays could actually reproduce a fraction of that? Now add motion and transform them into ever changing fractals, etc. Then add windows of apps with different colour management settings on that one display. Change the lighting conditions of your room, turn off the AC. 
Maybe, if you had one of these…
