You tell me. I think it's a killer song. The video shows you how the depth changes. The vocals are doubled but is it an 'effect' ? You can see them singing. It's not a "wide" mix.
IMO it's cool. The whole video and how it frames the audio. It basically depicts the concepts everyone is trying to learn. Depth, width, no crazy reverb, good balance, focus instruments moving into place with other instruments moving back yet remaining supportive.
