User preference towards HDR10 playback strategies by video player applications.

Modern HDR video playback strategies often involve adjustments by industry stakeholders, such as applying different Electro-Optical Transfer Functions (EOTFs), modifying peak luminance, or altering color characteristics, to enhance visual appeal. These modifications, however, can deviate from the original
artistic intent. Understanding observer preferences for such alterations is crucial, especially for smartphone playback under diverse ambient lighting. This study aims to pilot an assessment of user preferences for different HDR playback strategies on smartphones, focusing on EOTF, luminance, and color reproduction. The challenge lies in balancing these factors to enhance visual comfort and overall experience without compromising visual quality.
