A display with a transparent screen and then behind the transparent screen is an eink display.
When I wanted the eink mode the screen goes completely transparent and only uses the eink display. When I want a full colour high resolution display the ink goes black and the transparent display displays the colour content. Best of both worlds.
If transparent displays are cheap enough that they put them on fridges at the supermarket, clearly they’ve come down in costs enough for consumer electronics.
Interesting, both are sold, namely transparent screens with e.g LG and eInk monitors e.g Dasung so… could make for a cool prototype. I imagine though that studying the costs, economical and ecological, a “boring” screen might be better in most cases.

Look up the Mobvoi Ticwatch Pro 3. I have that watch and it has something like that, but not with e-ink
Technically speaking LED displays are transparent. You would just need a good backlight. It would be a good DIY project.
