What Color Gamut means ?
Color gamut spec of a TV is a measure of the range of colors that it can produce.
A TV with poor color accuracy will produce undersaturated/washed out colors that will spoil the immersion.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC, DCI P3 Adobe RGB and rec.2020.
In case of this TV, its color gamut is specified in DCI P3.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
Now, next in the list of important specifications that will impact your experience is Static Contrast.
The importance of static contrast ratio
A TV with low static contrast ratio will not produce deep blacks and can bleed backlight as shown below:

The static contrast ratio of above TV is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will show both dark gray and black as black, thus lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 5600 : 1., enough to produce deep blacks. For the record, it also comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10, HDR10+ and HLG (Hybrid Log Gamma).
Coming to brightness, it is capable of producing a maximum brightness of 700 nits. The panel of this TV is powered by Direct LED (Full-Array Local Dimming) backlight. This amount of brightness is good enough even for a room with sun's rays in!
Gaming Performance
If you are going to use a TV other than using it as a TV — say as a PC monitor or Gaming, you should take a TV that features the lowest input lag. For gaming, both the input lag and response time affects the performance.
The input lag on this TV is 11 ms and its minimum response time is 7 ms. It is acceptable for both casual and competitive/FPS games.
What is Input Lag and Why it matters ?
This lag is the amount of time at which device inputs changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
