It's very unlikely. Asymptomatic infections of aerosol spread respiratory diseases are not exclusive to sars-cov-2. Most people get asymptomatically infected with Influenza a every single year and often infect others without even realizing it. The more likely guess is that once you have humoral/serum immunity to protect the body proper you just get the upper respiratory infection (since mucosal tissues are not protected by humoral immunity significantly). And that mucosal only infection is less likely to cause serious disease.
