weird they make the US and UK versions with different software based enhancements? But I am sure that the Samsung website said local dimming for the H8000 and the 4k model above it (just checked). As far as the F8000.. the reviews I read stated pretty significant uniformity issues without engaging the local dimming (but excellent uniformity after that was engaged). For those that had no issues even with it turned off I guess it may have been luck of the draw. I know I was pretty unlucky with my first 60in 7100 and 2 Sony 850As. But, my 55in 7100 currently looks awesome, prob put that in the bedroom and place whatever 65in I decide on in the living room.. if the H8000 in the US show similarly negative reviews id lean towards the F8000.
