I have only one instance of ceiling smear in my listening area. Since then I have never again smacked a mosquito on white paint with a rolled up magazine.
I don't think it really degraded sound. but the visual effect was not good. Eventually I had to paint over it and the problem was solved. Does this answer your question or am I just bugging you?
