If you are aiming for the most selective schools it is probably worth a retake. With test-optional, a 1530 is now probably around or even below the median at those schools.
That said, if retaking will take away time from improving your transcript or distinguishing your application in other ways, you should probably skip it. The transcript is more important than ever, and even a 1600 isn’t going to cover for weaknesses there (unless perhaps you are significantly hooked).
Good luck.
