I think you might want a better way of phrasing that: it’s not the “full contact list” - most people would assume that includes names and all of the other metadata - and since it’s rate-limited there’s an interesting trade off where it’s not easy to brute-force but it is targetable if you are trying to track specific known people.

The name, profile pic, etc. is less relevant than the social graph itself. State actors already have phone number <-> name mappings at least about their own residents. If you are just curious about who's visa applications to deny because according to data collected by your IMSI-catcher many of their contacts have participated in an anti-government protest, then the name etc. isn't really relevant.
