Picture Quality
After screen size and resolution, the next important spec of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV comes with a DCI P3 coverage of 100%, which is equivalent to 136.36% sRGB. The color quality on this TV should be Lifelike!
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that it can show.
A display with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.
Different manufacturers use different measurement standards to specify color gamut. Such as — sRGB (standard RGB), NTSC, DCI P3 etc.
In case of this TV, its color gamut is specified using DCI P3.
But don't worry, here 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 can bleed backlight as shown in the images below:

The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is 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.
This TV features a static contrast ratio of 8000:1., good enough to display deep blacks and eye-catching visuals. The panel comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 32X.
As for brightness, it can go as bright as 250 nits with the help of Mini LED backlight.
Gaming Performance
Now if you are planning to use a TV other than using it as a TV — like as a PC monitor or Gaming, you should take a TV with lowest input lag. For gaming, both input lag and response time impacts the performance.
The input lag on the Samsung QN75QN95B is 6 ms and its minimum response time is N/A. For a TV, its the best you can get for gaming.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your key-presses/mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 75 inches vertically and 65.77 inches horizontally.
Coming to thickness, it is 0.7 inches thick. It weighs 31.3 kgs and 10 kgs extra if you include stand. So plan your space accordingly.
