Can likebook invert everything at a global system level?

Back to Onyx. If you're in Koreader or AlreaderX, there is no reason to exit to system as you have many, and frankly better ways of navigating to and opening books from within the apps. No reason to exit to system as long as you are only reading books. I do this all the time.

Rest assured, the night mode on Onyx with AlreaderX and Koreader is very nice for sensitive eyes. I lower the light very low and put on orange light. The letters are gold on black background. Very nice. I have very sensitive eyes and have no problem. You must allow the screen to flash occasionally to reset e-ink screen to prevent ghosting, but it is not disturbing, and I have very sensitive eyes.
