Let’s address the elephant in the room. Captain America: The First Avenger uses a specific visual technique: desaturation with selective color pop (think The Road to Perdition). The skin tones are often pale; the blues are muted.

The slightly softer texture of 720p actually helps blend the digital effects with the practical sets. the blues are muted.
