Yes. You can recover these permanently deleted files as long as they have not been overwritten. When files are deleted from your iOS devices, they are not entirely gone. iOS stores them in another location that you can't access within the OS. These files are only fully deleted when you overwrite them with new files.
When the "Recently Deleted" folder is cleared after 30 days, you can still use a third-party app like iFindit to recover the permanently deleted files.
