I recently purchased an LG 77CX 4K OLED (self lit LED pixels) (it's not a backlit TV) .
The LG replaces a 65 inch Sharp HD LCD display, which in it's day was superb and has always been quite pleasant and clear.
As many are now aware, OLED displays can produce perfect blacks, as the pixels are simply off to represent black. This leads to dramatically better picture quality in some conditions. Examples might include a star field with bright and dim stars and a bright looming planet, while watching a Science Fiction movie at night in a dark room. Absolute and utter perfection, and the letterbox "bars" on the top and bottom don't show up at all, nice.
Unfortunately, those perfect blacks translate over to a person's black hair on normal TV shows, and instead of seeing a hairstyle, one sees a black area, devoid of detail. Yes, one can adjust brightness and contrast (and other stuff too) to get back the detail, but it's just not really as good as a backlit LCD tv with regard to this. This is called "Crushed Black"
The colors are spectacular, the response time is good, and the picture does not have the digital artifacts of motion processing that some lesser TV's do.
So, there is much good, and some downside. Overall, since I'm a space movie nut, it was a perfect purchase.
Here is an enhanced example of a backlit LCD vs OLED for perfect blacks.
The pic below does "kind of" display the apparent lack of detail in the blacks that is so common on OLED tv's. It's not this bad, but it's there.
Interestingly, there is also more detail visible in many scenes, on OLED tv's, as the contrast is infinite. Look at the tree on the left.
