Question catalytic converter repair itself?

Recently did a tune up on '93 300e 2.8 and it runs great! Before the tuneup it had irregular miss and ran poorly, no power, etc. I wonder if the catalytic converter suffered any permanent damage due to the unburned fuel that was going into the exhaust or will it sorta "clean" itself?
Thanks, Al

The OE converters are pretty stout, and they would have to get red hot to do any permanent damage. Mine is still good with almost 200K miles on the clock.
