There are already, they are usually used only for display brightness, not color adjustment.
Some devices do use them to adjust the white balance of the screen but this is generally considered unnecessary as the eye will quite happily do this itself. A lot of cameras also do automatic white balancing otherwise we'd notice much greater shifts between natural and artificial lighting as you used to when working with real film.
But I think the paper is investigating more subtle effects (flowers look very different to insects than they do to us) such as IR levels.
