Why Converting SDR to HDR Involves More Than Just Brightening the Image

The paper presents a pixel‑level statistical study of the ASC StEM2 test film, building a three‑layer physical‑perceptual comparison of EXR, SDR and HDR masters, revealing that about 82 % of image regions can be restored through a restrained restoration process while the remaining areas require targeted semantic adjustments, offering concrete guidance for AI‑driven HDR conversion and industry standards.
