I don't know how you pulled that off Wolf. Did you use the same profile and expose and only changed from Cine2/Cine4/Slog?  Cause when I did this test (same profile, same exposure) here is what I got: Cine2: Cine4: Slog: And the Cine4 uncorrected (0-255 range clipped): You can see that the midtones are the same for Cine2 and Cine4. You can see it also in the YC waveform on the right.
