Nah, Melakon and Trevanian are right. We saw the wavering, transparent nacelle defect for years on our old TVs. HD and a big flatscreen just make it stand out even more.
On some of the Galileo 7 shots back in the 60s, you could even make out the garbage mattes against the starfield backgrounds. I think they tried to clean it up a little bit, but in those first season episodes, they were still trying to adapt motion picture techniques to television and it didn't always work.
