Here is what it's looks like converted with a matrix only color profile, then exported to sRGB:

With color patches (from 11*11px average):

Do that again and put in the Lab values.

The hue angle shifts in the darker of the skin sample pairs are towards yellow, not green.

That could be due to the lighting. I don't find them offensive. Are you sure you're color-normal?

Not affended at all.
My professional activities include training, with a vast majority of male worker, so this is something I'm precautious with.

Yes, I'm am color normal. I was checked several times, including for my former work, it was mandatory for some of my activities.

In this particular example, it may be the lighting. Too many unknowns.
Like I said, this example is used as an illustration only.

What is puzzling me is that I noticed such shift in a vast majority of my shots. With direct sunlight, in the shadow, in extrior, in interior, with flash...

To be fair, they look fine on my screen, or at least well within tolerance. The hue shifts do look more yellow than green (to me).

I find screen calibration can be a little tricky with some displays, so you may want to try it again, or try a different method.

Or check the ambient lighting in your office or wherever you are editing your images. Even having coloured walls can throw off your perceptual colour balance.
