I have the exact paint used on the walls in this room and figured out how to make the right pattern with a roller. So now fixing dirty bits of walls is pretty funny, I just touch up a place here and there, wait for it to dry, do a second pass and nobody can tell. and yeah the acrylic caulk CAN be painted over. It's just funny in that it obviously isn't porous, so when the paint is wet, the normal wall is a bit darker and then there are these very white acrylic spots
