I may have found an explanation, apparently e-ink are sensible to UV light and long exposure can cause a degradation of contrast.
As it turn out I left my KLC near a window while turned off directly exposed to the sun and "Barsoom omnibus" cover on... for at least a few weeks

This sucks but at least now I know what to do or at least what not to do with e-ink devices and it took me 10s of hours of usage to notice it... So It could be worst.

Anyway protect your screens everyone!
