Pretty sure the lengthy idling during warm up was / is being calculated by the onboard average fuel consumption metrics.

Same here.
Last winter was cold and snowy so mine sat long enough for the defroster to melt some ice. I averaged (by computer) 7.3 liters per 100 kilometers (32 mpg). This year it has bee almost ice and snow free so I jump in let it drop from high idle and drive off and have averaged 6.8 L/100Kms (34 mpg) . My driving is very regular and my average MPG does not waver one little bit so the only difference between the two is how long the car sat idling last winter.
The 6.8 figure is also my summer average when the car never idled past high and has not moved from that number since last April.
