I am using an iMac with a built in P3 display. These are using a color space commonly referred to as P3D65, with P3 primaries, D65 whitepoint, and sRGB gamma. ACES1.1 includes a new profile called P3D65, and as it is using the D65 whitepoint, I assumed if was targeted towards desktop monitors, rather than cinema projectors. Though, it is apparently using a 2.6 gamma. What is the reason for this? Is there any practical use case for a D65, 2.6 gamma combination? For now, I modified the profile, adding a 2.6->sRGB gamma correction at the end. Could you modify the P3D65 to use an sRGB gamma, or add a new profile, so that iMac monitors are supported?
