Moved sites to staging and back without updating the serialized data

A while back I rebuilt a bunch of sites to switch from the Enfold page builder to the Gutenberg block editor. I basically copied the sites to a staging environment (staging.siteurl.com), rebuilt the sites, and then copied them back to the live site (siteurl.com). When I updated the database for each move, I did a search and replace in Notepad++ (FIND: siteurl.com REPLACE: staging.siteurl.com >> FIND: staging.siteurl.com REPLACE: siteurl.com).

All the live sites are working fine. However, I have recently discovered about how data are serialized in the WordPress database through s:X, where X = the number of characters in the url. I know now that I should use a plugin like Better Search Replace to export a database to/from a staging site, which updates the serialized value. However, since I didn’t, I have a few concerns:

Is this something I should be worried about on these live sites?

What impacts does broken serialized data have (the staging sites seemed to work fine when the serialized data didn’t match the urls due to the appended staging.)?
