I understand the concept of removing blue color to see fluorescent pop and to highlight color pigment better, since led are narrow band lights which means it’s selective on A much smaller range of wavelength very much like a black light. Your eyes is very dynamic to visible wavelength that are usually related to colors you see. Certain filter used will remove and add back a certain color or perceived wavelength which your eyes can see. Thus highlights the color pigment better. It’s the same way when switching white balance on a camera to warmer kelvin which is a global mask to put back color overall it is no different from adding a filter to filter out some blues and bring out the colors florences under blue.
I get all that too, but for me when I am buying a coral for my tank, I want to have an idea of what it is going to look like when I am sitting in my recliner, sipping my bourbon and admiring my tank. I don't wear coral glasses when I look at the tank. I don't have my tank wrapped in film.
So for me personally when I go to a store, and it is part of the reason I go to a store and not shop online, is at the store you can have an idea of what the color of a coral will actually look like.
My favorite LFS up in Portland used to have their SPS tanks all on the same system. But they had 5 different tanks plumbed in. Each tank had different lights. You could actually see what the coral would look like, under your lights. That was pretty cool.
I guess I am just getting old and don't understand the new fads. I think the corals look good enough without trying to use things like film, and glasses to change their appearance.
