Correct. There's extended content insofar as epilogues and alike in the Patreon version but as far as it being as a complete story with answers to the mystery and conclusion to the story, this version has all that.
The caveat though is this version is a little behind insofar as some revisions made in the Patreon version both for clarification and QoL in some scenes when it comes to explaining some of the central themes a bit better.
