I'd take up your ENVI RPC support question with the vendors of the ENVI

As to why you aren't seeing the RPCs, I am suspicious of the use of
TIFFRewriteDirectory() - I have found it quirky to use in the past
though I don't recall the details.  I'd start testing the RPC support
with a newly written file, instead of trying to update an existing file
in place.
