I once bought a small E-Paper display [1] for a Raspi, and was very disappointed with the refresh rate, it was useless.
I wanted to use it to display room temperature and electrical information like home power consumption, solar panel power generation and stuff like that, and expected a refresh rate of around 1 update per second.
Having it blink and do stuff for around 7 seconds just to redraw the next frame made me send it back and replace it with a small LCD touchscreen [2].

Edit:
Look at all that needs to happen just to update the minute counter as well as the temperature and humidity. It certainly is faster than the colored display I bought, but still, do you really want such a flashing display? https://youtu.be/v9sNzmtMSXo?t=164
