I don't have any examples on hand. But with large amount of time I have found myself with over the past year to watch a lot of content, I too have noticed even some of the last episodics to be shot on film (2005-2010 range) are very noticeable. I have also seen some features from the 90s that looked really clean in comparison. Lots of things go into that, from how much the camera department "cared", what film stock was used, what film processor was used, etc. Towards the end of mass film production, there were fewer and fewer labs left. During they heyday, the soups used in the processing where in constant use. As demand lowered, the soups kind of stagnated especially in the shops financially strapped.

Film is fickle to be sure.
