In the context of Japanese media, "quality" can sometimes refer to the state of the file relative to the source. While Japanese law requires specific optical censorship, higher-quality rips often come from high-definition master sources (like Blu-ray discs) rather than low-resolution digital streams. "Extra quality" suggests the file is as close to the master source as possible, preserving the director's intended lighting and color grading.
When a brand provides these, the designation becomes useful for procurement managers, technicians, and informed consumers. Without them, “extra quality” risks becoming an empty differentiator that exploits buyer heuristics. sone127 extra quality
