I have watch many of the episodes and they have clean up the images very nicely. The only sad thing is the quality of the moral statements at the end of the show are original and look very cloudy. !
Are you referring to the sky
looking cloudy, or the picture quality? The reason I ask is that in the first season (episodes 1-15), all those morals were shot on the same day and it was raining at the time, so "cloudy" would be right! If, on the other hand, you're referring to picture quality, bear in mind that Warner Bros. were only able to find original film elements for the season 2 morals. All of the season 1 and season 3 morals had to be sourced from off-air VHS tapes that were recorded way back in 1980, on some of the earliest VCRs, and given the technology (remember, HQ hadn't even been invented for VHS by then), the likelihood of the person recording using LP instead of SP, the likelihood that CBS was using dirty/battered 16mm prints, and the likelihood that the off-air reception wasn't perfect anyway, all work against the picture quality. That being said, those morals look quite good, considering the source, and WB are to be commended for including them (and the option to play them from within the episode), because if it weren't for super-fans fighting for them, those morals could very well have been left out entirely, or gotten restricted to bonus features only (like BCI did with Isis
