Thanks, I agree about the accessibility setting. I know the iPhone at least doesn't actually use sRGB so the numbers are bound to be a bit off, but I'm surprised it's that far off.
Also, I'd note for modern iOS even just in dark mode the writer is in "black/white", while it's your own messages that are "blue" or "green" depending on whether its RCS so readability is less of an issue.
