Do you think that subtracting for example the R channel or the B channel instead of G would be different?

Probably. The normal spectral density of our world has "typically" a maximum in the green/yellow area (this is also why plants are green - most efficient part of the spectrum), and thus a good degree of energy ends up in the green channel.

Plants are green because they *don't* absorb green/yellow light, they absorb red and blue light.

Silly me, got too tired. You're right.

So long,
