It looks like the tip is delaminating. This is probably more due to a tip pik or Ultimate Tip Tool than hitting the floor, though that certainly didn't help. I see scratches in line with what appears to be a gap in the tip layers.
Did you test it to try to pull the tip apart before cutting it off? Could've possibly saved a ferrule replacement, but with that glue gap/line, replacing it was probably a smart move.
Out of curiosity, was the ferrule threaded on or slip-fit?
The tip has only been on there for less than a month, it is a Kamui Brown Soft, which doesn't mean it hasn't delaminated, was just giving a time frame for the life of the tip is all.
I did not test it to try and pull it apart, I took a razor blade and cut it off and it cut off SO easily that it just popped right off, no glue residue left on the ferrule at all, the tip came off so nice and clean that it LOOKS like you could sand the back and re-use it (I only said it LOOKED like it could be re-used, not that I WAS going to re-use it,lol).
The ferrule was a slip on, NO threads
