To clarify, if the display is showing a white image will it heat up less in any measurable way compared to if it’s off and just showing black?

What about LCD? Switching the state of a cell results in mechanical changes, which might influence how much sunlight it absorbs (even if it’s minuscule compared to the heat generated by the backlight)
LCDs are designed to filter out extremely specific types of light, and in a specific direction.
It’s true that the changing optical properties of each crystal could affect the albedo, but whether white or black is more effective is beyond my knowledge. It might even be neither, but green instead.
