I think the solution is a dual eink and oled display. Overlay a “transparent” oled on top of an epaper screen and use the oled to display colour images and video while using the epaper for static monochrome regions. I’m not sure that current “transparent” oled technology is transparent and thin enough though.

This sounds really similar to https://www.mobvoi.com/us/pages/ticwatchpro https://www.mobvoi.com/us/pages/ticwatchpro which is a Smartwatch with a dual layer display, one of them is e-ink, the other is an AMOLED display.

  Do a search for hybrid eink LCD display; Apple and others were looking into this 10 years ago; the Pixel Qi's 3qi displays were apparently manufactured and used in at least some products, then Apple applied for a more complex patent as well. As far as I can tell, both systems seem to use a layered display. https://www.pcworld.com/article/165724/bye_bye_kindle_netbook_readers_arrive.html https://www.pcworld.com/article/165724/bye_bye_kindle_netboo... https://arstechnica.com/gadgets/2011/04/apple-exploring-hybrid-e-inklcd-display-for-idevices/ https://arstechnica.com/gadgets/2011/04/apple-exploring-hybr...
