Do you keep the screen constantly on (with dimming but still on)? I had the same for a thermostat I made and the pixel burn on those screens are terrible. I would add offsetting to mitigate it. (Periodically render stuff with small random offsets) kudos!

Yep, I do. I used this kind of screen in another project, but it took years to burn in (and that one was completely static). The screen only costs $3-4 or so, so I can just replace it if it becomes an issue, but you are quite correct that it's going to be a problem.
