What “Extra Quality” Means Extra quality refers to enhancements beyond standard-definition or typical streaming releases. This includes higher resolution (1080p, 4K), greater bitrate for video and audio, advanced codecs (HEVC/H.265, AV1), lossless or near-lossless audio tracks (Dolby TrueHD, DTS-HD MA, Dolby Atmos), accurate color grading and HDR (HDR10, Dolby Vision), and clean, artifact-free encodes. It also encompasses thoughtful packaging: intact subtitles, proper chapter markers, correct aspect ratios, and minimal post-processing that might introduce noise or distortion.
