- What do you call a blockchain that actually follows the Bitcoin white paper?
You call it BITCOIN... an actual/real Bitcoin. This is what Bitcoin SV is.
- What do you call something that uses Bitcoin label in its name while not working as per the Bitcoin white paper?
You call that a scam.. a FAKE... and people who are promoting/shilling it should be exposed as SCAMMERS, aka LIARS.

Bitcoin is BSV, not BTC, nor BCH or anything else that uses Bitcoin in the name... name is a just a label.
It is how the blockchain/system WORKS that is the only thing that can be used to define what is Bitcoin and what is a fake/copy/scam.
