The L,M6200 does not have local dimming. LG calls its edge-lit with local dimming tech "LED Plus." The 6200 does feature LED Plus. The feature begins at the LM6700.
Perhaps the local dimming option is baked into the firmware and is accessible through the 6200's service menu (some LG sets from 2011 were like this), but the 6200 does not officially support local dimming.
