What Color Gamut means ?
Color gamut specification of a TV is a measure of the range of colors that the display can display.
A panel with poor color accuracy will produce washed out colors that will spoil your immersive experience.

But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV similarly impacts its picture quality.
Why its important?
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.
Also, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 8000:1., enough to display deep blacks and eye-catching visuals. For the record, it also comes with local dimming backlight technology which is a plus.
HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 1500 are also supported on this TV.

What is Input Lag and Why it matters ?
This lag is the amount of time at which your key-presses or mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
