Exactly! When I started using dark mode, it felt so much more pleasant for my eyes. After a while I realized this was because I was in generally dark environments a lot, so I started to switch up my environment instead: I.e. light up the room with a large ceiling lamp instead of just a small reading lamp on a desk etc.
I noticed when I'm working in the morning or generally when it's bright outside, it's sooo much more relaxing with black on white text. With night mode, I'd need to up the brightness way more to be able to comfortably read and type. It was sort of a revelation to me because the "night mode is better" mindset was so engrained into my mind at that point.
iOS was late to the dark theme train, but they did it right. One setting can change between light and dark depending on time of day, sunset times, etc.
