Details

HDR video being correctly displayed is a start, but we need to also handle the transfer functions correctly inside Canvas2D, WebGL and WebGPU, with WebGPU being the highest priority of these (as supporting it in the most modern API gives web developers a good option for compatibility while we build out the other APIs).

WebGPU does not use the ColorProfileConversionDesc in Colorspaces.h, and does not currently implement anything more than equivalents of what used to be PiecewiseGammaDesc in that header, but those are good places to start looking for integration.
