Same, i simply cannot find any other explanation for it. Apparently a significant amount of the population cannot do white-balancing in their head.
I have to assume they still experience the more physical white-balancing from light depleting the stuff in cone cells though: that thing where if you close one eye for a bit while looking at a sunny landscape, then open it and compare to the other eye by alternating which one you close; you'll see the world tinted.. i think it's blue-green-ish and red-ish depending on the eye. Different tint depending on the eye, at least.
