To quote
BT.2020, aka Rec.2020 (so called because it's supposed to be adopted by the year 2020) is actually a collection of standards, including the aforementioned 10-bit color depth, and like color depth it refers to the breadth of colors a panel is capable of displaying.

BT.2020 differs from the currently used Rec.709 standard, its use results in a larger span of colors being available to TV viewers, which more accurately capture the colors we can see in the real world.

Well its not really UHD lite as it is the proper resolution for it. Just because it isn't HDR it doesn't make it lite. Many 4K TVs don't even support HDR.
