Fair point, but I bet that making Firefox take 0.1W less on average is vastly more work that fixing a TV image. And if you write blog post about it, maybe other people can fix their TV with less work.
There are other ways to improve the planet as well. If everyone spent 2 hours a year removing washed up waste from the beaches, it would have made a big difference.

How did you manage to find the issue?
I noticed the screen only died when playing videos and always died at the same point if I rewatched a video. Notably, greyscale videos never caused the issue. Then I went through a video frame by frame to get to the frame it died on. Then I erased parts of the frame to find which part caused it. Eventually I found that if the red or blue pixel in the 481st column and the green pixel in the 482nd column have a differe…
I wish you could do this with phones. I know more than one person stuck with a crappy pOLED screen with that terrible green tint to the bottom third of the panel.
Sounds like you should be able to do this by just modifying Red Moon to draw a more complex overlay. If the entire screen is affected equally, the stock app may just be all you need!
I need this for my Android phone to compensate for a burnt-in image.
I don't think Android has an easy to use global shader system, so you'll be stuck with overlay windows and the incompatibility they have with banking apps/DRM crapware that locks you out of your own screen without root access.

Saving the monitor, releasing the diy reduces a (minor) head end of the problem that is not only leading to long waste in a landfill, but also metals and plastics in water.
Love the hacker mindset. Once the problem is solved, the underlying issue loses its appeal :)
Clever solution! It kind of reminds me of when I sometimes run sound through customized EQ and compression to compensate for crappy speakers. My approach is not quite as scientific as this though, just "tweak until it sounds good." I didn't know there was a version of MPC with a live shader editor, that is also very cool. This is actually a pretty good use case for such a feature.
This is almost identical to a problem I'm trying to solve, which is to turn a potato-quality picture of a sheet of paper into a clean scan, turning whatever levels of gray conform the paper background become a uniform #ffffff white. The obvious solutions (equalizing, converting to bitmap, …) don't work because what's white in the top left (say #ccc) is wildly different from what's white in the bottom right (say #888)…
If you want to preserve aliasing and also color generally, I'm sadly not aware of any open source solution for that. Various scanner apps seem to do it with varying degrees of success; I'd be curious if there's a standard algorithm for it. It feels related to the de-curving algorithms that take a book page and make it flat. So you'd be modeling both the page curvature and black/white values simultaneously. Seems possible for general lighting/shadow, but wouldn't work for reflectivity from camera flash.
