There is no active light generation with eInk, so "burn-in" is a physical impossibility. Image retention is a bit of a phenomena with eInk but it does not have long term effects like phosphor "burn-in" with CRT displays. Many eInk controllers use a black flash during page changes to eliminate the ghosting caused by the short term image retention. In any case, static displays are nothing to worry about with eInk.
