Is it be safe to say, that the direction of the clubhead after impact would peel away the illusion of Angle and Arc appraoches since Angle still goes straight and Arc curves inward?
I'm not sure I understand what you mean, Mike, but I'll go ahead and answer anyway: "I don't think so."
Even post-Impact, the player sees "through" the Plane and thus the Angle and Arc of Approach Delivery Lines that are actually on the Plane appear on the ground.
