Will it be apparent if I didn't seat the toilet on the wax ring correctly?

The wax ring on our toilet failed so I replaced it with a new one. The flange looked fine and I think I got the toilet seated correctly, it was hard for me to line up by myself. I put the ring on the flange and then set the toilet. I was able to bolt it down securely and it doesn't move or rock.

I poured a few 3 gallon buckets of water into it and there wasn't any water around the base. I tried to get a paper towel under the base but could only do it part of the way around.

This is the first time I've done this and I'm paranoid about water damage. If I didn't get the wax ring set correctly would it be easy to notice, or could I have a small leak I can't detect?
