Based on pictures posted on these forums, Voyages emit significantly more blue than red or green near the bottom of the screen. The total brightness decreases from bottom to top and the blue gets dimmer significantly faster than the red and green. By the top of the Voyage screen, the blue is usually significantly dimmer than the red and green.

Whether this is enough to suppress melatonin production seems to be an open question.
