Nearly all displays are incapable of accurately representing colors at high brightness (L=100) levels. You can clearly see the sRGB gamut is quite narrow within the CIELAB color space at (L=100). The CIELAB color space represents all colors perceptible by humans in daylight. https://en.wikipedia.org/wiki/File:SRGB_gamut_within_CIELAB_color_space_mesh.webm https://en.wikipedia.org/wiki/File:SRGB_gamut_within_CIELAB_... It is clear that higher brightness levels worsen color volume (cubes at the bottom of page 4) https://www.researchgate.net/publication/323273667_Color_volumes_in_lab_and_ICtCp_color_spaces_for_viewing_angle_color_characterization_of_QLED_and_OLED_HDRWCG_displays https://www.researchgate.net/publication/323273667_Color_vol...
