I would say no. Were it not your question, you wouldn't go and "correct" OP's memories of the book, so you shouldn't in your case either. You posted the question as you remembered the book, and that was what you remembered, so the question really can't be "incorrect."
What I've usually seen in any case where the suggested (presumably correct) work disagrees with details of the question is to call out the points of disagreement. If OP accepts that answer then it is a tacit acknowledgement of their mis-recollections, and even then we tend to discourage people from "correcting" their question.
As Valorum notes below, the same details you mis-remembered in your question might also be details that potential future searchers might get wrong too. (Especially if you've conflated the work you're searching for with a sequel, another book by the same author around the same time, a different book with a similar premise, etc.) In that case the "incorrect" question could actually be more useful than one that is strictly correct.
