The only time my ball 'explores' his cage is when I put him back in it after I've handled him. Even then he'll do a lap at best and then right back into the hide. My cal king on the other hand is a very active snake who 'enjoys' moving absolutely everything around in his tank he can. He's also the only one of my snakes who seems to prefer being out of the cage, but that's probably because he's a more active species. I've read A LOT of care sheets that said that changing things up is 'good' for the snake, but my experience says otherwise. My ball broke one of the branches I had in the tank so I took it out and he refused food for the next two weeks. That being said it was probably more the stress of suddenly falling rather than removing the branch, but you never really know. Now he's back on feed and hits ANYTHING with fur so hard I swear he kills prey on impact. Just my two cents, I'm no expert.
