Good.

And conversely, said individuals, unaware of individual image gamma settings, are dismissing GC as "washed out" exactly in the same scenarios.

Consider this:

I have a chair. I have pretended to be clueless and I set the image gamma for the chair texture to be equal to 1. Meanwhile in render settings I enable GC at 2.2.

What do I see? A washed out chair with improved shadow luminance. I erroneously conclude that GC washes out colors.

It does not wash out colors. This is not GC. This is gamma change, not correction. When you misconfigure the gamma values, it is no longer correction. It is an arbitrary change.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
