That's the older, not mini LED version.
Also, anything after the ? on an Amazon URL, you can remove.
It's a mini LED TV, so no, the pricing isn't really higher than similar TVs on the market, as mini LED TVs are still expensive, if not as expensive as OLED. The 144 Hz refresh rate also puts this in a very small category of TVs.
The only similar TV that I'm aware of and that's widely available, is the Class U7 from Hisense, which admittedly is slightly cheaper in 55 to 75-inch sizes, but more expensive in 85-inches.
