You're so right. What Sony was doing with mini LED last year, and just under 500 dimming zones, was blowing everybody else out of the water. This year, Sony introduced much more dimming zone control to make it more OLED-like. It works so well that Sony is making their top flagship TV a mini LED, called the Bravia 9. Check out how much better the backlighting system is:
Still, nothing yet matches the better colorspace of QD-OLED, and Sony managed to improve brightness on it too, so the second flagship in line will be the Bravia 8 with a QD-OLED panel. Sony buyers can take their pick and put a Bravia 9 in a bright room or a Bravia 8 in a light-controlled room.
This all begs the question—when will Sony get their hands on Tandem OLED?
