The color mapping method you use does not make it LWF or not.
To setup LWF:
Customize->Preferences->Gamma and LUT
Enable Gamma and LUT Correction
Enable radio button Gamma, set the spinner to 2.2
Optionally set the Input Bitmap Gamma to 2.2, output to 1.0
in your color mapping rendering settings to 2.2
