The Samsung JS7000 SUHD TV's picture quality is a mixed bag. It has a great viewing angle and low motion blur. However, it has poor blacks and bad uniformity.
Feature-wise, the Samsung JS7000 is simply a JU6500 but with a wider color gamut. The picture quality is completely different, though. It has less motion blur and a better viewing angle, but worse contrast and uniformity.
We reviewed the 55" Samsung UN55JS7000 (panel version: EH01). It has a PLS LCD panel (a sub category of the IPS family), which is why it has poor contrast and good viewing angle. It is the second Samsung that we reviewed with such panel, the first one being the smaller UN32J4000.
The 50" and 60" models use VA panels and are expected to have better contrast ratios and worse viewing angles.
The contrast ratio is really poor on this TV. It has an IPS panel, and produces gray blacks. Note that the 50" and 60" models don't have IPS panels and would have better contrast.
It is advertised as a full array backlight, but the 'Smart LED' feature is not even in the menu, so it is a probably an error on Samsung's website.
The advantage of LCD TVs with a poor contrast ratio like this one is the color accuracy at an angle, which is great. The 50" and 60" models use VA panels and have narrower viewing angle.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
It doesn't support 24p, so it has the 3:2 pulldown judder in movies. This is a small and consistent judder, so most people don't see it.
The input lag is low when turning on 'Game Mode' under 'System' - 'General'. In conjunction with the low motion blur, it is a great gaming TV.
For 4k @ 60Hz @ 4:4:4, turn on PC mode as well as UHD Color.
