Well, I like Dark Mode on all the things. But there is no arguing that more light make my pupils contract and there for there is more depth of focus (like high F number in photography) and things are easier to read with a variety of eye deviations. My wife always puts our TV in a very dim setting and complains about headache when I set it to max brightness. But I really get tired after watching a dim screen for 10+ min.
