Am I missing something? The innovation is to ... dim LEDs so that full brightness is... more than 100%...

HDR specifies a brightness. Apple is playing HDR videos at the proper brightness when the rest of the OS might be turned down.

That plus P3 gamut means a video playing on a display is closer to what a filmmaker intended.

What's cool is: 1) 4-year old Macs have become HDR laptops and 2) the implementation is subtle- you get full brightness in the HDR video without having the rest of the UI blast to full brightness.

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.
