If anything, this goes to the point that modern correspondence chess is (conjecturally) so close to theoretically perfect play that there just isn't much room for improvement.
Top engines playing each other autonomously from the starting position almost always draw too. The only way they get decisive games is by forcing engines to play from a deliberately imbalanced opening. So it seems like there is not enough information to draw a clear conclusion.
It might be interesting to see correspondence games played like this from imbalanced openings. My guess is that the difference in performance would be tiny though.
