Picture Quality
Now, the very next spec of a display that will impact your viewing experience is Color Gamut.
LG did not provide a color gamut specification for this TV. So we have to take a guess.
Considering the TV features amassive 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. Undoubtedly The color accuracy on this TV will be Lifelike! It will produce color accurate images out of the box.
What is Color gamut ?
Color gamut spec of a display is a measure of the range of colors that the display can show.
What this means is, this specification determines the ability of a display to produce accurate colors. A TV 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 etc. It is upto the manufacturer which one they choose.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
Next in the list that will impact your experience is Static Contrast.
The importance of static contrast ratio
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that may look dusty as shown below.

As you can imagine, this will rob your experience considerably.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will show both dark gray and black as black, thus lesser detail overall.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
There is no mention of this specification in this TV's official datasheet. So we have to make an assumptionagain based on the TV's other specs. The static contrast ratio of this TV would be surely atleast 3000:1. As you know, this TV comes with a VA panel, these panels by nature have high contrast ratios.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
Coming to brightness, it is capable of producing a maximum luminance of 250 nits, which is powered by Direct LED backlight.
Gaming Performance
If you aren't into gaming, you can safely ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you should get a TV that features the lowest input lag and response time.
Unfortunately, LG did not specify the input lag on this unit. But since this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your 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.
But ideally, look for a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. However, there is no Swivel, Tilt or Pivot feature support in this TV.
