No official Blu-ray is released in 480p. 480p is always a downscale from 1080p or 720p sources. The official DVDs are 480p (NTSC) but usually in English only.
Downloading large files requires robust internet connectivity. For viewers managing metered data plans or dealing with slower, unstable internet connections, 480p downloads ensure a smooth, uninterrupted acquisition of the full season without data exhaustion.
