Seems like this might a wrong assumption (or CF changed something). Just tested one of my own sites that's on the free plan and it has "sni=plaintext".

There are occasional false positives, but querying different Cloudflare data centers usually resolves this. I've found that switching VPN servers (which routes through different CF edge locations) eventually gives the correct result.
