Is the oil temperature reading taken before or after the oil cooler? 2.7

[MsPickles]

In the standard gauge set, the oil temperature is available as one of the digital gauges to display. But I'm curious, is that a temperature reading of the oil temperature before it passes through the oil cooler/heat exchanger or after it?
It seems that if the temperature is collected after the heat exchanger, it is more representative (rough estimate) of the coolant temperature as well. If it's taken before the exchanger, like a tap off of the oil galley or after oil pump/filter, then it may be more representative of the oil temp after coming off the internals temperature/block temp.

I'm not sure, but I will say there is not going to be a huge difference. It isn't like the oil after the cooler is 40 degrees cooler. The loop is constant and has high flow.

Transmissions are different, pan temperature vs torque converter will have a major difference.
