I get calls nowadays with caller id telemarketer or suspected spam or similar, is this what it does?

A little yes, a little no. Your phone knows when it's receiving a call from an unauthenticated number, but it would be very unreliable to use this metric alone to decide when a call is untrustworthy. My understanding is that carrier telemetry is what drives the final yes/no verdict.
