The static contrast ratio (1000:1+) you mention is different from effective perceived contrast after tone mapping - manufacturers' specs measure black-to-white

The static contrast ratio (1000:1+) you mention is different from effective perceived contrast after tone mapping - manufacturers' specs measure black-to-white in ideal conditions, while tone mapping algorithms must compress real-world luminance ranges (millions:1) into that limited display range while preserving perceptual detail.
