They are actually not that incredible IMO, the main issue underwater is loss of red light which is quickly absorbed followed by yellow and so on, by about 10m the red is all but gone so any algorithm trying to work without artificial light breaks down. The corrections needed for UW images are really not that complicated if you have enough red, the levels tool can do the balancing within a minute or so if you know what you are doing. If the water is green it may take an extra step to pull to a pleasing balance point using curves but still very quick.
