There is a reason why real HDR monitors have minimum requirement of 1000 cd/m² for monitors and 4000 cd/m² for projectors. It is because realistic mid-day scene requires 700 cd/m² and sky over 2000 cd/m². Anything less and day scenes will start to look more like like dusk or dawn. Some low quality theatres are killing 3D cinema with not enough brightness, because even mid-day bright scenes looks dark and de-colourised, because human eye is switching to monochromatic vision under low light conditions.

Human eye experiences up to 90 000 nits (cd/m²) per day. These popular standards exists to cover this:
* HDR10 for LED (0.05 nits black, ≥1000 nits peak, 10-bit color depth)
* HDR10 for OLED (0.0005 nits black, ≥540 nits peak, 10-bit color depth)
* Dolby Vision for Cinema (0 nits black, ≥4000 nits peak, 12-bit color depth)
