Ah right thanks for the clarification. I don’t believe my screen has that issue, as if I enable reader view on a website and enable dark mode (so the background behind the text is pure black), by zooming into an area where there’s no text the screen is completely black, even with the display on full brightness. However, if I do the same thing with the screen on minimum brightness, I can notice a very slight hint of light coming from the screen ... but it’s extremely faint.
That aside, everything definitely has a greenish tint at very low brightness levels - to the point where the screen almost looks monkchromatic ... but with faint green instead of white! 😤
