You can dim the whole OS expect the video being played. This can’t be done anywhere else at this point.

That video can have a very bright sky, for instance. You can have a bright sky and a blinding text box or neither in other OSs.

It’s also a very bright display in its own right, with 1600 nits vs the 300-400 of a regular one. And 1,000,000:1 contrast as well.
