Neither description is accurate of what Apple did. On a local match, they would send alternate (encrypted) hashes. If those matched as well, they’d send a downscaled version of the file for human review if I recall correctly. Not quite the same as PhotoDNA but also not as alarmist as “they’re uploading your entire photo library for analysis”. The vast majority of analysis is offline and only the assets that matched local AND remote would get uploaded.
