I absolutely love it compared to my current iPhone. Super comfortable eink display that looks like paper. Messenger works great with a monochrome theme. And great battery too since screen doesn't emit light. Love using it for reading, especially right before bed. If you want to learn more check out the r/eink subreddit.
Good call, when I upload my camera test video I'll include a small section of viewing the photos taken as well on the eink screen. But for still photos it will look pretty similar to how b&w mode looks like on normal phones.
