Decision TreesInclude decision trees for greyscale, gamma and CMS calibration dependent on display controls.HighCOMPLETE

It is sometimes helpful to do an SDR base calibration and then base the HDR calibration on that. Sometimes this is the only option for some displays. Auto-calibration may also play a role.HighJul ’22
