My take on that is that replacing the first section RVR with pilot assessment only comes into play when RVR is not available.
Yes, but as you say that section refers to when no RVR is available. However AMC1 SPA.LVO low visibility operations includes the note:
“The reported RVR value representative of the initial part of the take-off run can be replaced by pilot assessment.“
So my take is that even a TDZ RVR that is reported can be replaced by pilot assessment.
