Even if Gemini Lake supports encoding of 10 bit (HEVC, VP9), I don't know what this means for me. With 10 bit a main feature of HDR is supported, i.e. we can have more than 16.7 Mio. colors/17.6 stops. Basically this is already HDR.
That's not what is usually taken as the meaning of HDR. 10-bit video alone isn't HDR - after all 10-bit video has been in widespread use in SDR broadcast production areas since the days of Standard Def. For HDR to be supported on a display, the display really needs to follow an HDR EOTF (Electro Optical Transfer Function - a bit like gamma) and have a bright enough maximum light level, and dark enough black level, for this EOTF to display something with a higher dynamic range than conventional SDR.
