I am shocked with the contrast ratio numbers on the H8000 in that review. The black level on the H8000 is almost twice that than on the F8000. Uniformity has also suffered, probably because of the difficulty of evenly distributing light across a curved screen. My F8000 has nearly perfect uniformity with no DSE whatsoever, the F8000 was praised for it's backlight uniformity. Now I'm even more glad I got the F8000.
This is rather bizzare. Sony's W950B 1080p flagship for 2014 was supremely disappointing compared to the previous W900A flagship. And now Samsung's 1080p flagship is rather disappointing as well but not nearly as much as the Sony.
Honestly, if you're into a 1080p set get the F8000. If you're interested in a 2014 set rather than the F8000, the flat 4K flagship may be the best option. That H8000 review also states that the 4K curved model has similar backlight uniformity issues. I foresaw these quality problems many many months ago as manufacturers were looking towards gimmicks to sell their TV's and not improve the picture quality. The W950B was a HUGE step backwards in terms of picture quality and the H8000 is a slight step backwards as well (lower contrast ratio, poor uniformity). Stay away from both of these TV's.
