No, the images are only decryptable after a threshold (which appears to be about 30) is breached. If you've received 30 pieces of CSAM from WhatsApp contacts without blocking them and/or stopping WhatsApp from automatically saving to iCloud, I gotta say, it's on you at that point.

Just a side point, a single WhatsApp message can contain up to 30 images. 30 is the literal max of a single message. So ONE MESSAGE could theoretically contain enough images to trip this threshold.

A fair point, yes, and somewhat scuppering towards my argument.

You’re aware that people sleep at night, and phones for the most part don’t, right?

Victim blaming because of failure to meet some seemingly arbitrary limit, ok.
