The answer lies here:

                                                                        0.5
                                                                         |
right now, if the camera is pointing this way --->   the results are  0------1.0
                                                                         |
                                                                        0.5

So the whole normal result needs to get adjusted.
I'm not sure if there's a way to rotate the results by 90 deg along the r and g
axes...
