This isn't true — the native 1600 nits mode only uses 1600 nits for HDR content. Regular content/OS UI/etc is still limited to much less brightness.

Check out this HDR YouTube video at this timestamp to see how bright white actually is at 1600 nits:

Here's a photo of my XDR display with a pure white rectangle in Figma next to white content in an HDR video, with the display set to the 1600 nits mode:

Huh, I was not aware of that. I will take a closer look.
