I don’t think the formulas are rendered in reader view. (iOS Safari)
In the browser (iOS Safari) I use an extension (dark reader) to give it a dark theme, and the formulas render just fine there.

QQ: Do the math formulas render properly in reader mode for you? (On my test with Chrome, the answer seems to be no.)
