Yeah, it's not easy to see, I missed it earlier too. You have to look at RFC 5803 and RFC 3112 together. RFC 3112 says
thatthe overall format is "<scheme>$<authInfo>$<authValue>", and RFC5803 says that for SCRAM, scheme is "SCRAM-SHA-256"
(forour variant), authInfo is "<iteration count>:<salt>" and authValue is "<StoredKey>:<ServerKey>"
They really should've included examples in those RFCs.
