Picture Quality
Now, the very next spec of a display that will impact your viewing experience is Color Gamut.
LG has not provided a color gamut specification for this TV. So we have to take a guess. Now, since the TV features a big 65 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 accuracy on this TV will be Lifelike! It will produce color accurate images by default.
What Color Gamut means ?
Color gamut spec of a display indicates the range of colors that the display can show.
Meaning, this specification determines the ability of a display to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 etc.
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.
Other than color accuracy, the static contrast specification of a TV has equally important role in picture quality.
Understanding Static Contrast
A TV with low static contrast ratio will not produce deep enough blacks and possibly can bleed backlight as below:

The above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
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, so lesser detail overall.
This TV features a static contrast ratio of 8000:1., well enough to achieve deep blacks. For the record, it also comes with local dimming feature which is a plus.
Dolby Vision, HDR10 Pro, HLG (Hybrid Log Gamma) and Dolby Vision IQ are also supported on this TV.
Coming to brightness, the peak brightness the LG 65QNED85UQA can produce is 250 nits. The panel of this TV is powered by Mini LED backlight technology.
Gaming Performance
If you are planning to use your TV other than using it as a TV — say as a PC monitor or for gaming purposes, you would want to take a TV that features the lowest input lag. For gaming however, both the input lag and response time impacts the performance.
Sadly, LG did not specify the input lag on this unit. But as this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the amount of time at which your inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that has an input lag and response time of < 20ms.
Ergonomics and Dimensions
Coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 400 x 400 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
The width of this TV is 57.17 inches while its height is 35.59 inches.
It is just 1.77 inches thick. It weighs approximately 30.2 Kgs, another 0.4 kgs if you include stand. So plan your space accordingly.
