You can buy on Amazon Prime Video, Apple TV, or Vudu, but beware of compression. Streaming 4K caps out at roughly 25 Mbps. The physical 4K Blu-ray disc runs at 60–80 Mbps. For a film filled with fast-moving snowflakes and wide landscape shots, the physical disc avoids the "banding" (visible color stripes in the sky) that plagues the streaming version.

The inclusion of HDR10 is the standout feature. It enhances the contrast, making the "Let It Go" sequence truly pop with radiant glows along ice blocks and brilliant sparkles in individual ice crystals.
