Yeah, no, you don't understand how Laserdiscs work at an RF level at all. A dropout is easily determined by a total loss of carrier tracking as well as a massive SNR spike above or below anything that could remotely be encoded in a normal signal.
Dropouts aren't even remotely "white noise", and cannot even remotely be confused with a mastering or post-production technique when analyzing the underlying RF signal.
