CSS trick/bug to display a brighter white by exploiting browsers' HDR capability and Apple's EDR system

Visit https://fff.kidi.ng for the demo.

How does this work?

By combining an HDR video with CSS hack, the white color of the text becomes even brighter.

#whiter {
  filter: brightness(10);
  backdrop-filter: brightness(1);
}

When a HDR-capable browser encounters one, it switches to HDR mode. The exact reason for this behavior is not yet known.
