The only explanation I can think of is that the bayer filter array of the sensor is not completely flat. Even a small bulge in manometers scale can cause unmatched color channels. Time to return the faulty unit.

Yep, I'm taking it back tomorrow first thing after work. Now that I have a reliable way of verifying it, it will be trivial to check in store if the replacement is fine or not.
