Implement a feature to reduce the brightness of whites
White color can cause eye fatigue, especially for those who spend hours in front of the screen or for those who has eye sensitivity to light, migraines etc. Not everyone likes to use dark mode.
iOS, for example, has this, but is named as "reduce whitepoint level":
It's a great a11y setting. It can also be useful for devices that have a minimum brightness that is not really... minimum.
This is already available when enabling the Zoom feature, maybe the code can be re-used?
