I checked my 55 f1.2 more carefully, and with a little imagination
thrown in I think I see a slight falloff of the yellowing at the
edges.  It is not a gradual, but a more of a sudden change near the
edge.  BTW, a skylight filter reduces the visibility of the
yellowing.

from the center to the periphery  to the extent expected, but
expectations are empirical given the absence of thickness
measurements.
