Sometimes it’s actually better with dark background on direct sun.
If we are talking about devices screen, white background kinda goes yellow on direct sun and contrast reduces. But black background goes dark grey and less light gets reelected back to the eyes.
If we are talking old school paper ( SHOCKING i know ). It’s close to unreadable on direct sun when paper is white because it shines back too bright, it hurts eyes but black paper it much more comfy on eyes.
Note: Reason why black on white was used historicaly is most likely economical. (Less paint, easy to maintain.) If papyrus naturally turned black, all written text might have been in “dark mode” from the beginning.
The trick when directly in the sun is to push the button that turns the screen is off and then place the phone in a pocket and make sure your fingers do not touch the phone.
Use dark mode directly in the sun and tell me how well you can read the text

Turn up your screen brightness?
The difference between black on white and white on black is negligible, especially with modern displays
I can read it just fine. Is something wrong with your eyes?
