iTunes video quality drop?

[Naiera]

I noticed during last week’s episode of The Fosters that the video quality seems to have gone south. It’s the same thing this week. I also noticed macroblocking at one point during The Flash last week. Of course, that’s a rather “high speed” show, but I’ve never noticed it being that obvious before.

Has anyone else noticed something like this? Are the files still the same size? Or is someone mucking things up with the encodes?
