> periodic batch [] real-time detection network

What's the realistic difference here between "my phone scans the photo on upload to iCloud Photos" and "iCloud Photos scans the photo when it's uploaded"?

Latency of upload doesn't come into play here because the scan results are part of the uploaded photo metadata; they're not submitted distinctly according to Apple's technical description.

(And given the threshold needed before you can decrypt any of the tagged photos with the client side system, the server side scanning would be much more "real-time" in this case, no?)
