Your test on a human doesn’t make much sense, especially the conclusion that the Pixel sensor can’t be used on people. FDA has much more credibility in this field.😉

For starters, your FLIR sensor has a very low resolution, and its settings are clearly not designed for measuring body temperature.

Contactless medical thermometers usually apply a coefficient to approximate body temperature because your forehead is never exactly 36.6°C.
It seems the Pixel does something similar in body temperature mode.

Instead of doing a random test on a dog, you could have compared the Pixel sensor to a medical thermometer. That would show its accuracy is within the stated accuracy, meaning it’s perfectly fine for checking if you’re sick or not.
Surprisingly, the sensor turned out to be very useful for our family, as it measures temperature quickly and has shown no discrepancies compared to medical devices so far.

You need to understand some physics...
Not everything has the same IR emission profile. A kitchen IR temperature gun will be calibrated closest to the 'black body' emission profile because you will likely aim it at your cast-iron pan to check its temperature. A thermal imaging camera will be calibrated to a rough average of real world things, but you can usually change this in the settings (I can with my thermal imaging camera). The Google sensor is calibrated to the emission profile of human skin. Pointing the phone and the flir imager at things and expecting the same result simply belies your lack of understanding.
