Do left or right door choice matter in Metrico+?

I'm also curious about this and it doesn't look like it does beyond changing which part will turn into a robotic part.

In the original game you’d be confronted with a choice of two exits to a level, and be greeted by a pie chart declaring how many players went out through what door. It had no bearing on the game itself, and was more of a statement on the illusion of choice and agency. Here we have a story of the player character gradually becoming mechanical, your choice of exit door deciding what limb will turn robotic next.

I think that's part of the "Decide what your story is in Metrico+" from the Steam description. Basically the game doesn't really have a story so you can make one up.
