Picture Quality
After screen size and resolution, the next important spec of a display that will impact your viewing experience is its Color Gamut.
LG did not provide a color gamut specification for this TV. So we have to take a guess.Now, since the TV features an OLED panel, there is no need to worry about color accuracy. Because OLED panels ALWAYS come with over 100% sRGB coverage.
Understanding the Color Gamut Specification
Color gamut specification of a display indicates the range of colors that the display can show.
A TV with poor color reproduction will produce washed out colors that will spoil the immersion.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 Adobe RGB, rec.2020.
But you don't need to worry about that, here 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 substantially.
Understanding the static contrast ratio of a TV
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast defines the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 will produce black images something like this:

Note that, such TVs are also prone backlight bleeds that will impact your experience — as shown below.

Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
Given this TV comes with an OLED panel, its static constrast would be 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.
As for brightness, it is can achieve a peak luminance of 250 nits.
Gaming Performance
If you are not interested in gaming, 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, make sure to take a TV that features the lowest input lag and response time.
The input lag on the LG OLED55G29LD 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 key-presses or mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that has an input lag and response time of < 20ms.
