InfluxDB

Back in the day before operating systems copied the feature there were tons of Android apps that added a red shift on top of your screen by drawing over other applications (i.e. https://play.google.com/store/apps/details?id=com.csk.app.sh..., https://github.com/LibreShift/red-moon). This usually breaks/doesn't work with banking apps and other such secure contexts but for most apps that's probably fine.
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 use AutoEQ (https://github.com/jaakkopasanen/AutoEq) for my headphones. It works by "parsing frequency response measurements and producing equalization settings which correct the headphone to a neutral sound". They also have a huge database of already measured and equalized data, which is what I use.

I use it to make sure a 'sensitive' pixel on my screen never turns on (it's a row of pixels which, if the difference between it and the pixels to the side have more than a certain difference in brightness, the whole screen fails - presumably due to a power supply fault in the column driver circuitry).

Do you use night shift in build, or twilight app? Night shift is kinda warm orange even with maxed out filter level and in twilight you can go solid red or whatever you desire. Which works better for you? Does it hurt amoled screens in any way?
