The benchmark BlockToJsonVerbose only tests generating (and destroying) the JSON data structure, but serializing into a string is also a performance critical aspect of the RPC calls. Also, use ankerl::nanobench::doNotOptimizeAway to make sure the compiler can't optimize the result of the calls away.
