Hard to say, specially considering a possibly sketchy compression tester. Apparently the cylinder wasn't firing much ... hence the "miss". I'm not knowledgeable enough to know what kind of conditions that might create in a cylinder. Unburned fuel can wash the cylinder walls, which isn't great for them. Carbon on the valves and combustion chamber could have softened up and moved around, possibly holding a valve open a bit.
Hopefully someone else with chime in, but if you didn't notice that you had a miss to begin with, I can only assume it will run better than it did before. Hard to imagine any serious damage was done.
