. . . putting it in FX is EXACTLY where it belongs because it's a creative effect.
Agreed. Apropos of which, I'm discovering ways to use (abuse?) the
Dehaze slider that have nothing to do with neutralizing atmospheric haze—although, to be sure, it often works very well for that. Attached: two versions of a 2013 photo of a young couple making a "selfie," reflected in a glass wall, that I snapped with a point-and-shoot camera at the Museum of Modern Art in New York. I'm not even sure why I bothered to save it, and it certainly will never qualify as fine art, but cranking up LR's Dehaze value to 60 made it an interesting picture, as far as I'm concerned.
I don't think we should get overly exercised about the names the LR developers give various adjustments. Every one of them is a creative effect if it helps you create the image you want.
