Dolby Vision is a proprietary HDR and Wide Colour gamut (WCG) system from Dolby. It’s being sold into the TV and film market. Dolby Vision is based around the use of a very well characterised display during the shading or grading process where an expert adjusts get the required look, generating added metadata which is fed to Dolby Vision equipped displays. Dolby Vision uses PQ as the EOTF of its mastering and domestic displays.
