Understanding the Color Gamut Specification
Color gamut spec of a TV indicates the range of colors that it can display.
Meaning, this specification indicates the ability of a display to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 to name a few.
As for this TV its color gamut is specified in DCI P3.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast specification of a TV holds almost equal role in picture quality.
Understanding the static contrast ratio of a TV
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Also, such displays are likely to suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Obviously this will affect your viewing experience, especially in a dark room.
Other than black levels, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.
This TV is rated with a static contrast ratio of 10000:1., good enough to achieve deep blacks. For the record, it also comes with local dimming feature which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 64X.
Coming to brightness, the peak brightness it can achieve is 250 nits. The backlight of this TV is powered by Mini LED technology.
If you are going to use a TV other than watching videos — like as a PC monitor or for gaming purposes, you should take a TV that features the lowest input lag. For gaming, both input lag and response time impacts the performance.

Understanding Input lag and response time
This lag is the latency at which device inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
