Picture Quality
Now, the very next spec of a display that defines picture quality is Color Gamut.
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that. As this TV features a big 50 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. The color quality on this TV will be Lifelike! Meaning it is capable of producing accurate colors out of the box.
What is Color gamut ?
Color gamut spec of a TV indicates the range of colors that it can produce.
Put Simply, this specification tells the ability of a TV to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB, rec.2020. 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, the static contrast of a TV also impacts its picture quality.
Why its important?
A TV with low static contrast ratio will not produce deep enough blacks and can bleed backlight as shown in the images below:

The static contrast ratio of above TV is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
Other than black levels, a TV with high constrast ratio enables 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., well enough to produce deep blacks and eye-catching visuals. The panel comes with local dimming backlight technology which is a plus.
HDR10, HDR10+, Dolby Vision, HLG (Hybrid Log Gamma) and Dolby Vision IQ are also supported on this TV, so that's a plus.
As for brightness, it is capable of producing a peak luminance of 250 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you are planning to use your TV only for content consumption, 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, you would want to take a TV with the lowest input lag and response time.
The input lag on this TV is 15 ms and its minimum response time is 8 ms. It is acceptable for both casual and competitive/FPS games alike.
Understanding Input lag and response time
This lag is the amount of time at which your 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.
Although for better experience, look for a TV that comes with an input lag and response time of less than 20ms.
