What Color Gamut means ?
Color gamut specification of a display is a measure of the range of colors that the TV can produce.
A display with poor color reproduction will produce undersaturated colors that will spoil the immersion.

After color gamut, next in the list of important specifications that will impact your experience is Static Contrast.
Understanding the static contrast ratio
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This defines the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 will produce black images something like this:
Apart from that, such TVs are also prone backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
This TV comes with a static contrast ratio of 8000:1., well enough to display deep blacks. For the record, it also comes with local dimming 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 32X.

What is Input lag ?
This lag is the amount of time at which key-presses or mouse movements changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, get a TV that comes with an input lag and response time of < 20ms.
