Hybrid does indeed include the 3D Cube mode.
But, its real application is to allow smaller 3D Cube profiling (say 10^3) in combination with a larger 1D profile set.
When you get to a 17^3 Cube profile size the benefits are negligible.
And unless you have a very, very good probe, that can read shadow detail well, you may actually introduce errors in the profile.
You wont see such errors in the final LUT as LightSpace uses some very special algorithms to deal with such reading errors.
But, there will be no benefit in the calibration compared to a standard 17^3 profiel.
