What do you mean by "more green"? I don't see any shaded green.

And I presume the black pixels are unregistered ISBNs?

I'd suggest you try a color blindness test. The green is very obvious, especially about 40% of the way down the whole image.
No, I see the green, but I don't see any shaded green. Though this has probably to do that ISBNs are distributed in blocks and every pixel is either red or green?
If you look closely there are definitely some brownish pixels and some dim greens.
