OK, I will accept that disclaimer.

In my limited experience, trying to enhance the contrast between
clouds and sky via the channel mixer can only go so far - eventually
I start to get visible artefacts, posterisation(?), whatever it is.

I said I accept your disclaimer, no need to prove it.

LOL. Good one. I thought that's what this was about. I'm still happy to hear
