As for the green tinge, you can try this:
On that point, it might be time to check the WB coefficients of your camera.
If your screen is properly calibrated to D65, just display a grey gradient on it, shoot it with your camera, then open the raw in darktable and do a spot-white balance on the whole ramp in the white balance module.
Finally, compare the RGB coeffs you got with the sampling with the “camera reference” ones, and report here in case of large shift.
You could use the picked values in place of the default ones of ‘camera reference’ and see if that eliminates the tinge; it’d give you a warning, but that’s OK in this case.
