It's not just you. I don't have any sources to link to, but 15 years ago a website was frowned upon for having light text on an (almost) black background because it was bad for readability and made your eyes strain. I tended to agree and find this dark mode craze quite curious because of how the industry has completely flipped its opinion. Maybe someone has sources/studies that contradict this, but that's my memory of the situation.
