While I understand where you come from, there is still a difference of the medium.
Eg: I have seen Blade (1998) on a VHS first, except it was a pirated copy of a pirated copy. It was a very dark, almost noir toned story, somewhat visually akin to Sin City. Years later, when I saw in a decent quality on a (still analog at that time) TV I didn't recognized it first. And again, years later on a digital TV it became just a bunch of ads for Snipes on a highly lit backdrops and ugly CGI. Somewhat similar, though not that jarring, is my story with Babylon 5. Even when it aired I could see the effects and CGI (they were pretty obvious most of the time) but now the difference of quality (and 38" vs 14") sometimes distracts from immersing to the story.
BTW only with Avatar I finally couldn't reliably distinguish where the CGI starts or ends, but it was a top notch one. I still see the "lame" CGI (especially when a fake motion blur is cranked up to 11) even on a high budget films, like all that comic book adaptations.
