The difference between the standard Blu-ray (1080p) and the UHD (2160p) release is "noticeable to significant."
The 2160p resolution provides four times the detail of standard 1080p. This is especially noticeable in the intricate period costumes, such as the textures of Claire’s fingerless knit gloves and thick shawls, as well as the fine facial details like pores and wrinkles.
