if you scroll about three-fifths of the way down, you come to a section "Outside the demo room". What Hi-Fi then hail a comparison between the 4k Samsung flatscreen UE65HU7500 and the new LG OLED 55EC930V. I'd be very interested to hear, from an official What Hi-Fi person, why they couldn't have got hold of the 55" version of the Samsung, as the OLED is available at only 55". It's pretty well known that a significant, and I would say that 65" compared to 55" is significant, size difference between two televisions being compared, favours the larger television. So, What Hi-Fi, why haven't you found a 55" Samsung???
At the TV shootout I attended in Leeds last year, it was the same; 65-inch LED lit LCD TVs with a 60-inch plasma and a 55-inch OLED. Yet the winners were plasma and OLED.
