Accept the 10-bit BT.2100 PQ display formats 0x8100070422000000 (red in the low bits) and 0x8100070400000000 (blue in the low bits) and convert them to 8-bit sRGB when presented: PQ EOTF, BT.2020 to BT.709 primaries, a luminance tone map whose white level is the tone-map luminance sceSystemServiceGetHdrToneMapLuminance reports (reference white min(203 nits, white level)), and the sRGB encoding. The conversion runs on the CPU for linear buffers and DCC clear values, in the color transfer shader for tiled guest buffers, and in the presentation pass for resident images. The three share the PQ EOTF table computed once in double precision. AI-assisted: yes
