Certainly some art critics and artists over-apply and over-think so-called 'golden' geometry. What I think is happening is very simple... that artists avoid regularity (e.g. two lights of the same color and intensity, exact center placement, exact placement at thirds, corner placement, two regions at the same angle, two hue spreads of equal sides on opposite sides of the RYB hue wheel etc etc). These loose 'rules' of avoidance can be confused with 'rules' of prescription such as color harmony, golden section etc.
