Picture Quality
Now, the very next spec of a display that will impact your viewing experience is its Color Gamut.
The TCL 85P735 features 75% DCI P3 color gamut coverage, which is equivalent to 102.27% sRGB coverage. Thus the color reproduction on this TV will be excellent! So your viewing experience would be immersive as this TV is capable of producing near accurate colors by default.
Understanding Color Gamut
Color gamut specification of a display is a measure of the range of colors that the display can produce.
Put Simply, this specification indicates the ability of a TV to produce accurate colors. A TV with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
For example, the color gamut of this TV is specified in DCI P3.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, you should look at the static contrast specification as it impacts the picture quality the same way.
Understanding the static contrast specification
A TV with low static contrast ratio will not produce deep blacks and possibly can bleed backlight as in the below image:

The above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
Also note, static contrast ratio and resolution go hand in hand when it comes to details. To put it into perspective, a TV with low contrast ratio will show both dark gray and black as black, so lesser detail overall.
This TV comes with a static contrast ratio of 5000 : 1., good enough to achieve deep blacks. For the record, it also comes with local dimming feature which is a plus.
HDR10, HLG (Hybrid Log Gamma) and Dolby Vision are also supported on this TV.
Coming to brightness, it is capable of producing a maximum brightness of 330 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you are not interested in gaming, you can ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you should get a TV with the lowest input lag and response time.
The input lag on the TCL 85P735 is 15 ms and its minimum response time is 8.5 ms. It is acceptable for both casual and competitive/FPS games alike.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your key-presses/mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that features an input lag and response time of less than 20ms.
