You can speculate like that if you wish, but that is pure speculation. Tesla makes "comfort and functionality" changes all the time, many of which have brought range improvements from better efficiencies. I would wager that the car is unchanged, and a 70 mph highway test would yield similar results to 2023.But Tesla never said how much their "comfort and functionality" improvements decreased range just that it was a factor. It could very well be the EPA's change accounts for 35 miles and Tesla's vibration change is the other 2 miles making 2 miles the REAL range reduction...which I can live with.
