2. Why "Extra Quality" Matters: Bitrate & Resolution Explained
When users demand "extra quality," they aren't just talking about 4K resolution. Many Smart TVs already support 4K. The issue is bitrate—the amount of data used per second of video.
- Standard YouTube App: Compresses video heavily to save bandwidth (AV1/VP9 codec at ~15 Mbps for 4K).
- Version 617 391 (Alleged feature): Forces VP9 Profile 2 (HDR) or locks the bitrate to a higher ceiling (~35-50 Mbps), resulting in fewer "blocky" shadows in dark scenes.
Users report that this specific version reduces the "gradient banding" (visible lines in the sky or shadows) that plagues standard YouTube streaming on large 65-inch+ screens.
