Suggested correction: This is in the questions as well. With the long amount of time the artists have to make an episode it's very hard that something like this would get by them. It's probably the device you watched it on.

Not true, watching a clip on Youtube and the episode on Disney+ the scratch is present. So it's not the device being used by the submitter.
