Blu-ray 4K Still Delivers More Detail Than Streaming
Ultra HD Blu-ray can devote far more data to video (up to 128 Mbps on 100GB discs) than streaming, which must adapt to network conditions and compress the signal, so Blu-ray generally preserves more detail; high‑bitrate streaming (e.g., 43–80 Mbps for Pure Stream) can narrow the gap, and local Plex Direct Play/Direct Stream can avoid recompression, but the key issue is how much picture information reaches your screen, not whether it comes from disc or the internet.
