What it demonstrates is that there are no missing green pixels. The green between the letters is exactly what should be expected once you take into account the background and the fringe around the letters.
if you start with an image with a halo and you paste a copy of that same image along with it's halo how could you not get anything but an image with a halo?
the two BIRTH's are identical right down to the exact same grey pixels in the bottom of the B and the top of the R.
You have proved for us what I have suspected all along the entire text was first typed out on a white background , selected where the white halo would still appear around the entire text because of the small size of the lettering and pasted intact onto a blank form.
