They stopped bothering. They had some demo screens a few years back, mira-something I think, and a few products that used it, but nobody bought it because the colors were terrible due to the entire "e-inks generally don't require backlights and so massive contrast issues" I think the tech got bought up and pretty much shoved in a corner somewhere
Mirasol display is I think what you're trying to recall. I still have one; a Kyobo Android 'tablet'. In typical tablet usage conditions (i.e. indoors, probably at night on a bed) then yes, mirasol displays and color e-ink screens never matched LCDs and SAMOLEDS. Mirasol was decent/serviceable imo while color e-ink has been truly terrible.
However in outdoor conditions (e.g. at the beach or a park) I still haven't seen any iPad or Samsung display as pleasing as my old mirasol display without backlight. If someone released a new mirasol display ereader today, I would buy it in a heartbeat
