Even in real estate raw images do not look natural, because our eye has greater dynamic range than camera sensors and colors are lost in the shades. But in underwater photography we hardly have any choice. If our goal was for everything to look natural, we won't spend money on strobes. And in the powerful artificial light they provide nothing looks natural anymore.
But natural look is not necessary photographer's goal. Bokeh, for example, is completely unnatural phenomenon, yet it is highly valued among portrait photographers. Or take BW photography which is an art in itself. Is our world BW? Hell, no, but lots of folks love it. So it all boils down to this simple question, "Do I like this enough to hang it on the wall?"
