Even when there is no flashing erase operation (which is basically just the whole page being erased), there is still an erase operation going on e-ink screens. I still believe the OP is in fact observing an erase operation, aka partial screen refresh, in action. More subtle perhaps than before due to the higher resolution of Kindle PW1/2 or because of a new algorithm.
