The disclosure describes a system and method for adjusting a backlight for a display for an electronic device. In the method, the following steps are provided: identifying a highest brightness value of an image for generation on the display; determining whether there is sufficient brightness headroom for the image based on the highest brightness value. If the brightness headroom is sufficient, then the method adjusts the image to create an adjusted image where elements of the adjusted image are boosted in brightness from the image based on the brightness headroom; and generates the adjusted image on the display. Finally, the method adjusts a backlight level to a lower adjusted backlight level for the adjusted image based on the brightness headroom.
