Samsung KS9500 is edge lit, meaning no local dimming. Samsung briefly mentioned a KS9800, which was not on display at CES 2016 that will come equipped with a full-array local dimming backlight there is no further information on it yet, and it will likely be available much later in 2016; not this Spring like the other 2016 models. There is no denying that Samsung KS9500 is a gorgeous TV. The edge lit backlight has allowed Samsung to make it much thinner than last year’s JS9500 model. Samsung calls it a "frameless curved design". It is not actually frameless but the bezel is flush with the front glass. In other words, Samsung has sacrificed a full backlight for a prettier TV. During a tech demo backroom session some of Samsung’s engineers elaborate on how they have managed to achieve such high brightness levels with an edge LED. They said that a combination of new "improved quantum dots", an edge lit "local dimming" system, and brighter LEDs have made it possible. From what could be gathered the KS9500 has 24 local dimming zones but the answer was a little muddy. Samsung talked about peak brightness. The KS9500 - and all other new SUHD models - are "UHD Premium" certified, meaning that the TVs can peak at more than 1000 nits when reproducing HDR content. Samsung confirmed that KS9500 can output 1000 nits luminance in up to a 10% window. The engineers said that KS9500 can reproduce almost the full DCI-P3 color gamut, more specifically 98% vs. last year’s 90% number. However, 98% DCI-P3 is of course relative only to the DCI-P3 reference. As HDR content is encoded in the Rec.2020 container, a TV might be capable of reproducing certain colors beyond the DCI-P3 gamut that are part of the larger Rec.2020 gamut, even if specified at "only" 98% DCI-P3. For example: if a TV has a red primary that is wider than the DCI-P3 gamut’s red primary but a green primary that is slightly smaller than DCI-P3’s green primary, it might only be specified as 98% DCI-P3 coverage but it will be able to reach some of the red tones specified in the larger Rec.2020 gamut.
