It is a Denso limiting-current type wideband sensor (as opposed to the pump-cell & reference cell type for Bosch sensors). I'm not sure what model it is, but considering this is still a very new car it's probably one of their latest ones (Plus 5.1, etc). Over the years wideband sensors have improved in accuracy and lightoff time, mostly for emissions purposes. See attached information.
Based on my experience, the Bosch sensors (LSU 4.2, 4.9 etc) are slightly more accurate at the rich end of the spectrum BUT to some extent it depends on how smart the controller and heater are, the placement of the sensor, etc. The two types of sensors (Denso vs Bosch) work on a little bit different principles.
