I haven't read any research on this, but this feels incorrect. If this is true, staring at red-tinged floodlight should do less to keep you awake than looking at a blue LED with masking tape over it.
It feels more likely that this is related to excitation of S cones -- which dimming the screen without changing the colour temperature would also accomplish, to a degree.
