What Color Gamut means ?
Color gamut spec of a TV is the measurement of the range of colors that the TV can display.
A panel with poor color accuracy will produce washed out colors that will spoil the immersion.
Different manufacturers use different units to define color gamut. Such as — sRGB, NTSC 1953, DCI P3 to name a few.
For example, the color gamut of this TV is specified in terms of 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, after color gamut, the static contrast of a TV also impacts its picture quality.
The importance of static contrast ratio
A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that look dusty as shown below.

As you imagine, this will impact your experience considerably.
Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
This TV comes with a static contrast ratio of Infinity:1.. So no need to worry about this at all.
HLG (Hybrid Log Gamma), HDR10+, HDR10 and Dolby Vision are also supported on this TV, so that's a plus.
Coming to brightness, it is can produce a maximum luminance of 800 nits.This amount of brightness is good enough even for a room with sun's rays in!
Gaming Performance
If you are not planning to game on this TV, you can safely ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to take a TV with the lowest input lag and response time.
The input lag on this TV is 20 ms and its minimum response time is 1 ms. It is good enough for casual and non-FPS games but is not suitable for competitive or FPS games.
What is Input Lag and Why it matters ?
This lag is the amount of time at which inputs changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that features an input lag and response time of < 20ms.
