I'm a simple man, and did something similar but with bash+mosquitto+imagemagick running on a Kindle. That's boring/been done, but what I want to talk about is screen burn-in. I've been displaying slight variations of the same image on an old Kidle paperwhite for a bit over 5 years! I've noticed NO burn-in at all. I'm doing partial updates every refresh (30 second refreshes), so the display will go 1+ years without a full refresh (~1 million partial refreshes a year). There's some retention when I first work with it, but clearing the screen and showing a full-screen pattern is enough to remove that retention entirely. Pretty impressive, and I am also impressed the old firmware stays attached to wifi for the whole time as well! Sometimes it can have trouble reconnecting (power outage, dog unplugged wifi, whatever), that's when I'll see if there's burn-in, probably once a year(ish).
