@Carlos-Sancho Than you should cycle through different colors and think about duty cycles. Do you absolutely need it on ALL THE TIME? Perhaps you can add a pushbutton to bring up a reading? In industrial plants that I've seen, this is what they do as constantly replacing LCD screens (or bulbs, depending on the age of the equipment) gets terribly wasteful and expensive.
And since it is the internet we're connected to, perhaps have an always on message bus, with the screen displaying when the pushbutton is pressed to compare network connectivity. It'd be a quick way to verify that your code or the network hasn't gone stale from a remote monitoring station, and it'd also protect you from burn in.
A final alternative is to add scrolling animations, or cycle which measurement is scrolling via above pushbutton.
Basically, add a button as a "JIT" duty cycle enabler. You'll be happier you did, and you don't even need to write software to create an electronic interrupt using a BJT or whatever. It'd be a nice experiment in low cost/low power/no code solutions.
