In fact, now that I take a second look at it, the source of brightness appears to be the polar ice regions and the shallows around the landmasses that contrast highly with the dark greens, browns and blues.
you could dull the ice, but it might end up looking to dirty or not like ice at all and more like sand.
As for the shallows they could be darkened slightly, but not much else can be done at this stage.
