You might be surprised how much water clarity you can enhance by playing with the black slider in Lightroom.

Yeah but this is different which is BTW mentioned in the video (@ 2:55)and quite obvious from the explanation of the method. Lightroom has no way of knowing what it should look like. Her algorithm does because of the reference card she uses. Simplified, the algorithm knows what red, green etc. is supposed to look like without the water. By looking at the reference card under water from it can calculate influence of underwater circumstances and apply the needed correction to the entire image. It's quite clever.
