@daringfireball No, it's not Warner or HBO Max that botched the episodes. They didn't bother to check them, but the problem is with the original studio, Lionsgate. It looks like LG went back to the original film negative for the early seasons (the crew switched to Arri Alexa and digital during season 5), rescanned them in 4K, but forgot that some shots featured CGI, like mattes to hide equipment or technicians. Hence these blunders. HBO Max simply has exclusive rights on the 4K versions.
