- deergomoo 3y agoThis is actually super interesting: for displays that can get bright enough for HDR content, but do not have self-illuminated pixels/local dimming zones/any other mechanism to display very dark content alongside very bright (like, say, most modern iPad and Mac screens), this is exactly what is happening. macOS/iPadOS cranks the backlight brightness up but then adds a black filter to the non-bright content to sim it back to “normal” levels. https://prolost.com/blog/edr https://prolost.com/blog/edr
