Still using iPhoto app on your Mac and working on an earlier macOS? Even your iPhoto library gets disappeared after Mac update, we can still restore.

No, actually macOS update won’t delete any photos stored on your Mac. If photo lost does happen after an update, it could be caused by some unexpected factors during the update process, such as power outage, malware or virus infection, data overwritten due to insufficient space, conflict between apps and the updated macOS system, etc.
Our Mac may store years or months of photos, they are valuable and we can’t afford to lose them. But chances are that they can be deleted or disappeared during the process of Mac upgrading. So, it is necessary to back up the entire Mac drive before upgrading to new Sonoma or Ventura or other versions. You can back up them to multiple devices or using cloud service such as Google Drive, Dropbox, etc.
Once data loss occurs, just stay calm, and follow the methods above to recover lost or disappeared photos on Mac after update. The most helpful and all-in-one solution I think is to install a Mac photo recovery software or service.
