Something I noticed about the big bang theory

In the early seasons(like season 2 for example) the colors on the show were a lot more muted. Watch this clip of footage from season 2 then compare it to this footage of season 7. See the difference? the colors on season 7 are a lot more vivid. It's almost like the vibrance slider was turned up among with the saturation. It gives newer episodes a weird almost home footage look. I don't mind it at all but now that I noticed it I can not unsee it
