Similar to Dolby Vision, HDR10+ is a royalty-free dynamic metadata format. Having both "DV" and "HDR10+" in a tag usually implies a "hybrid" or "multi-HDR" release that will work at peak performance on almost any modern 4K TV (Samsung, LG, Sony, etc.).

The tag is a hallmark of "boutique" digital encoding. It represents the intersection of classic cinema and cutting-edge artificial intelligence, designed for viewers who refuse to compromise on visual quality.

Standard 4K Blu-rays are excellent, but they are limited by the technology available at the time of the movie's release. Enthusiasts use "AI Enhancement" to revitalize older films, making them look like they were shot on modern digital cameras.
