[James2001]

Another look at the episode, and, like the end credit montage, Malcolm's opening link doesn't have the colour grading that's on the unedited studio tape either (once you find the exact take of the link that was used, he did so many! It's the one that begins at around the 32:40 mark on the video I uploaded). The colour grading kicks in as soon as it cuts to Shampoo though. Seems strange they'd splice in that link from a different source to the performance (and the link and performance are from the same take, it's not as if they edited in one of the other takes of the performance after the link)

Also noticed when doing this side by side comparison that the faux-letterbox bars are wider on the broadcast version than the studio tape:
