The turn of the century and big switch to digital that goes full force right when the 2000s start kind of changes things. Those old cartoons could still be passed off as looking sort of contemporary because of the way things were made in those few decades and even though a 60s or 70s cartoon might look old if you were watching them in the 90s, they really start to look old old as the 2000s and beyond happen (old doesn't mean bad btw).
Also it seems like the money all started going to CG animation at roughly the same time period and all those big budget CG movies are even more different looking. Like you could take 1970 to 1995 and then 1995 to 2005 and you can see much bigger changes in that 10 year window than you could in the 25 year window
