BSI Sensors for m4/3 cameras?

[capital]

I have not seen any micro four thirds cameras that state they have BSI sensors. The Panasonic LUMIX LX100 II press release states a "4/3-inch High Sensitivity MOS Sensor for the seventh generation model of Panasonic’s world-renowned LX high-end compact camera series."

Is there any indication this is Panasonic nomenclature for their BSI sensor?
