The Re:Zero Blu-ray Disc sets released in the United States from FUNimation Entertainment and in the United Kingdom from Anime Limited show color banding artifacts visible in some frames.
Re:Zero shipped on Blu-ray Disc in the U.S. on Tuesday and is slated for release in the U.K. on June 25.
The frames where it is noticeable show bands of color instead of a smooth gradient.
Disclosure: Justin Sevakis has authored other discs for Anime Limited.
