Picture Quality
Now, the very next specification of a display that will impact your viewing experience is its Color Gamut.
Hisense did not provide a color gamut rating for this TV. So we have to take a guess. Now, since the TV features a big 75 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. Undoubtedly The color quality on this TV should be Lifelike! It is capable of producing accurate colors by default.
Understanding the Color Gamut Specification
Color gamut spec of a TV is the measurement of the range of colors that the TV can display.
Meaning, it tells the ability of a display to produce accurate colors. A display with low color 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(most popular), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality the same way.
Understanding Static Contrast
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 in the below image.

As you see, this will affect your experience considerably.
Also, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 8000:1., well enough to achieve deep blacks. For the record, it also comes with local dimming backlight which is a plus.
Dolby Vision, Dolby Vision IQ, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV.
Coming to brightness, it can go as bright as 250 nits with the help of Direct LED (Full-Array Local Dimming) backlight.
Gaming Performance
If you aren't planning to game on this TV, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you should take a TV that features the lowest input lag and response time.
The input lag on this TV is 15 ms and its minimum response time is N/A. 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 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.
