For starters in light bending calculations the r coordinate is actually used as a physical distance so spatially speaking there is not much going on as space is now assumed spatially flat (e.g. rho is assumed equal to r). On the other hand light actually decelerates when attracted by a gravitational field and my intuition would say that is the reason for the 'double whammy' not spatial curvature. Surely I must be wrong, for my understanding is little, and greater minds on this website will obviously have no trouble at all to demonstrate I am wrong and lack understanding by using the appropriate formulas. So I remain.
