Once a preprint is marked as "published," its publication status and published DOI are never revisited again. In rare cases, this information changes. This paper, for example:
https://www.biorxiv.org/content/10.1101/151043v1
was initially listed with a published DOI that was identical to its preprint DOI. It was corrected on bioRxiv, but not in the Rxivist database.
