Picture Quality
Now, the next important feature of a display that will impact your viewing experience is its Color Gamut.
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that. Considering the TV features amassive 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 quality on this TV will be Lifelike! Meaning it is capable of producing color accurate images out of the box.
Understanding the Color Gamut Specification
Color gamut specification of a display is a measure of the range of colors that the TV can display.
In other words, this specification determines the ability of a display 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,sRGB (standard RGB), NTSC 1953, DCI P3 etc.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Now, next in the list that will impact your experience is Static Contrast.
Understanding the static contrast ratio
Static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such displays may suffer from backlight bleeds such as this:

Needless to say, this will rob your experience, especially in a dark room.
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.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 8000:1., well enough to display deep blacks and eye-catching visuals. The panel comes with local dimming backlight which is a plus.
HLG (Hybrid Log Gamma), HDR, HDR10 and Dolby Vision are also supported on this TV, so that's a plus.
As for brightness, it is capable of producing a maximum luminance of 350 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you are not planning to game on this TV, you can ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, you should get a TV with the lowest input lag and response time.
Sadly, Hitachi did not specify the input lag on this unit. Now, since this is not a cheap TV from Hitachi, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which your key-presses/mouse movements changes the content of your display. 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.
