touch-up on that DO looks "janky but right"!
One more trivia point: the fact of this frame being so tall, plus the 27.0 seatpost, points to it probably being Columbus SP tubing, or a mixed set with SP seat tube at least.

Very slight chance it's SPX tubing but I think it's a couple years too young for that, you could check with a good light in the butts of the main tubes next time you have the BB opened up and can look carefully (if you hadn't already). SPX (as does SLX) has helical ridges in the butts of those tubes, similar to what all SL (and above) steerers in Columbus forks will have.
