You not thinking of or considering GC doesn't invalidate GC, aeilkema. It merely means you never considered or thought to try something other than cranking up the lights when your materials appeared to render dark.
Someone comes out with a suggestion (GC your materials), I try it. I publish my tests. Then, if multiple runs of those tests prove conclusive, I change my practice. When something even better comes out (corrected-sRGB) I try it. I run tests. etc etc

Now, I'm going to have a go at Esther's suggestion. Or do you consider that a bad idea too?

BTW, what have your tests shown?
