Of course, even at perfect efficiency (which is not possible to achieve so far as I know, and it was already LED based), that tv would be too energy inefficient for consumer use and so it is many orders of magnitude (I think) brighter than today's tvs. So while the HDR tech can be mind-blowing, truly incredible, I think its implementation might be garbage for home use right now. Still, you're comparing those images on an SDR screen. Of course the HDR one looks flat. On even the lowest end HDR screen, the one on the left should have brighter looking whites than the one on the right has on even a very good SDR screen.
