Your paper glows with 300+ nit backlight? Also, paper is white "traditionally" (real traditional is parchment which is brown) because making white ink / white pencils is quite difficult. While white pencil tips exist today, they do a poor job in comparison to the dark gray pencil. Thus it is a matter of technical limitations on physical objects like paper, pens, pencils, and erasers... rather than a case of "white is the ultimate background color as proven by the paper industry"
Ever since I discovered dark mode, I can no longer use light mode; it burns my eyes. Aside from regular dark, I also like non-light sepia, if available.
I like dark mode better but I sometimes use light mode cause I use dark mode too much or I'm too lazy to change it to dark mode
if your screen is OLED, then yes. though not by too much for regular 30% to 50% brightness setting (3-9% saving) according to a research by people at Purdue University. it is at full brightness when the savings becomes more apparent, according to their findings. i'd also liked to remind everyone, if you use any of NU main site's dark mode, you'll probably have to change your highlight colors to accommodate the change https://www.novelupdates.com/reading-list/ click on Global Settings to change your highlight colors @Blitz if you ever update that thread, please add this info too.
Not all site have good dark mode, or I'm just too lazy to search. Usually I just use F.lux on pc (would recommend ) or just generic reading mode app on phone. Both are on permanently, f.lux auto adjust, while the other one I have to manually adjust day vs night so I don't burn my eye out unexpectedly.
not just OLED (which is surprisingly common in phones btw). True QDLEDs as well.... except AFAIK nobody is actually selling true QDLED's, instead samsung made some demo units and displayed them in shows but never sold them. instead some display call themselves quantum dot display but simply use a large singular quantum dot lightbulb as a backlight for an ordinary LCD screen. while a true QDLEDs will be like an OLEDs where each pixel emit its own light rather than restrict the light from a backlight. Also on LED backlit LCDs there is Dynamic dimming where the display is separated into 100 zones which can individually be dimmed to save power and increase contrast. There is also microLED where each individual pixel has their own individual LED backlight. allowing it to be dimmed the same way as OLED is... however AFAIK this is only been displayed as demo units and not sold https://en.wikipedia.org/wiki/MicroLED Also there is the LCD resting state. It varies by the LCD but the majority of them have black as their resting state, meaning it saves a very small amount of power compared to letting color through. Not nearly as much as the other technologies here though. https://www.scientificamerican.com/article/fact-or-fiction-black-is/
