Cutting out all the unlock world challeneges and intro cutscene from the full game run means that any%, even in its current unoptimized state, could go at least like 15 minutes lower. If it were somehow also able to be timed without level loading/level cutscenes, that would shave off a lot of time too.

I'm not sure how much lower it could go from it's current (roughly) 2 hours and 30 minute time. Sub 2 hours is probably possible. Especially any% because a lot of levels can easily be cheesed to be beaten in like 2 seconds when not having to collect every object.

I'm currently working on doing some any% runs of every world, so once I practice enough, I'll be able to get a much better any% record. Sub 2 is the goal, but I'm really excited to see how low it can go!

(Now 100%...that'll take some learning. This game is very finicky...)
