I'm not so sure that's right. If weight is increased, then sure, collective pitch angle has to increase to produce the necessary lift. Accordingly, aerodynamic load increases and servo transparency can ensue.
Stay with me for a minute; hypothetically, if the aircraft were to be climbed to an infinite altitude, i.e. into space. There would be no aerodynamic load so no servo transparency.
I know retreating blade stall is exacerbated by increased density altitude, but Servo Transparency? I've yet to be convinced.
