Kettleblack X was able to “confess” to the High Septon, sure he was a knight but how unlikely would it be for anyone to get an audience with this Pope-level figure? How about the requirements to meet in person the real Pope of the era. Bonus: better fictional conservative restorationist holy figure: High Sparrow or Young Pope?

Well, first off, the High Sparrow is an unusual High Septon who prides himself (heh) on his humility and service, so he’s a bit easier to get in contact with than most; second, Osney is confessing to having committed adultery with the Queen. That’s kind of a big deal and would probably get him routed up the Faith’s management structure regardless of who was at the top.
