– 10 Point White Balance controls can be used to calibrate both greyscale and gamma, for manual calibration.
– DisplayCal can create 3D LUTs (most accurate way to calibrate for movies) with a PC hooked up to a TV.
–MadVR is a video renderer that supports 3D LUTs. All I know of is a Windows version. You can run Windows through Boot Camp or through Virtual Machines on your MacBook.
Im also learning calibration myself too.
