Picture Quality
After screen size and resolution, the very next feature of a display that defines picture quality is Color Gamut.
This TV doesn't provide a color gamut specification, so we have to take a guess.
Since it comes with an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.
Understanding Color Gamut
Color gamut spec of a TV indicates the range of colors that it can show.
In other words, it determines the ability of a TV to produce accurate colors. A panel 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(most popular), NTSC, 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 will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast of a TV similarly impacts its picture quality.
Understanding the static contrast ratio of a TV
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 will look dusty as shown below.

As you can imagine, this will rob your experience considerably.
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.
This TV comes with a static contrast ratio of Infinity:1.. So no need to worry about this.
HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro are also supported on this TV.
Coming to brightness, the peak luminance the LG OLED83C2PUA can produce is 250 nits.
Gaming Performance
If you are planning to use your TV solely for content consumption, you can safely ignore these specs. 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 LG OLED83C2PUA is 5 ms and its minimum response time is 1 ms. Pick this one if you are a gamer.
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.
Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Coming to ergonomics — a VESA mount with interface size of 400 x 400 mm is provided for wall-mounting. However, there is no Swivel, Tilt or Pivot feature support on this TV.
The width of this TV is 74.31 inches while its height is 42.99 inches.
It is just 2.18 inches thick. It weighs approximately 32.3 KGs and an additional 9.3 kgs if you include stand. So plan your space accordingly.
