E-Ink displays were declared having a lifespan of 10 million switches per dot: you would have to do a study about how often the average pixel is changed, but if that value were 5s, the lifespan would be "five years of short week 9-to-5" - that is not bad.
I am not sure if A2 mode or Greyscale Update with frequent dot switching is a stress that makes the dots degrade faster (not simply "decrease the life count going towards the max", but "decreasing the max"). I supposed not dramatically.
those switches per dot ratings are fair, but another assumption here is that EPD takes a non-0 amount of time to move the ink particles in the fluid they are suspended in with a magnetic field. when you try to move them more than roughly 8-12hz it already uses more power than a normal screen and if you run it at even higher voltages and speeds the ink particles start to burst and lose shape, leading to a greying out of the panel quite rapidly (within a few months)
