And note the original Aura was the first Kobo ereader to use Regal technology to reduce ghosting.

That’s tremendously insightful. From an electrical engineering perspective it sounds counterintuitive… so much more logical that Not to electrically charge a pigment cell for it to remain at the bottom layer is 100% more efficient powerwise than to charge the upper layer for it to float upwards… else the device would always be consuming power to keep the lower pigments on the lower layer which we know eink doesn’t. And from a chemical/materials science one that the white dye would make the screen look much whiter on the spectrum. Big thanks.
