The pump you used might be out of calibration?
Very unlikely, states take pump calibration very seriously.

My truck is fairly accurate for the distance, especially at the bottom end. I can usually guess how much fuel is going in ±0.5-1 gal when I stop.

Temperature can affect the density of the gas too. However, I am sure that there is some built in headroom in the tank.

I've never gone that low. On other trucks I've found if you really slowly fill you can go above the nominal max gallons. However on my Powerboost that doesn't work. Also, in my observation when the DTE is <200 miles it is on the mark. My refills after that point have always been to the gallons appropriate for the consumed gallons fr the miles covered.

Indeed, but not really enough to matter for these situations. That was one of the contentious variables for spacex given they drastically cool down their fuels to fit more of them in the tanks. Part of this requires fueling as late as possible to keep the propellants cool and NASA doesn't like last second fueling with humans onboard. Even airliners require passengers to be removed from the aircraft while fueling.

Given the location of gas station fuel tanks, fuel being pumped from them will always be in the 50-60f range for the most part. Couldn't see this having any meaningful impact. A pump's metering on the the other hand could be a contributing factor.
