Other than the 55-inch screen size and 4K 2160p resolution, this screen has
HDR (aka HDR10) is supported, according to the product specs, and
Roku built-in to the TV (full 4K and HDR support).
Run Netflix, Amazon Instant Video, HBO, Vudu, and any Roku app directly on your TV.
When you view HDR compatible content (Netflix, YouTube, and Amazon do have HDR 4K content now), the contrast and brightness changes on parts of the screen to produce more life-like quality.
With HDR, brights look brighter and darks look darker for a more natural look.
This video explains people who upgraded from 1080p to 4K often did not notice much difference, until HDR was introduced.
For more explanation, here's an article,and a video.
Most other 55-inch TVs with HDR cost $600 and up.
Note, Blu-Ray players and discs do not support HDR.
New "Ultra Blu-Ray" supports HDR, but instead of buying new equipment, stream 4K HDR content from Netflix, Amazon, YouTube, and Vudu.
However with Net Neutrality set to be eliminated in the US on Thursday, unfortunately, the future of 4K HDR streaming video may be in jeopardy for a lot of Americans.
The FCC rules slated to replace Net Neutrality will enable cable companies to tamper with streaming video delivery as a way to generate revenue and unfairly compete for your TV viewing business by slowing competition.
Corporate cable channels and companies will start prioritizing their own content over others, like Verizon did with Netflix before Net Neutrality.
Most Americans have no choice who their home cable Internet company is, so switching to a different Internet provider is not even an option.
Most other stores sell this 2017 model for at least $450.
Other 55-inch TVs with similar specs sell for at least $500.
Even if you don't have anything that plays 4K video, this (like many other 2017 model 4K TVs) have built-in HDR which means brights are brighter and blacks and blacker.
Here's a video review and another video review.
Also, this model has Roku built-in, so you can stream videos over wifi without having to buy a Roku.
Roku has DirecTV Now and Playstation Vue live TV apps for watching cable channels without subscribing to cable TV, as well as a YouTube for watching videos uploaded to YouTube.
