I don't personally see it being an issue - the owner's manual says regular 87 octane is the recommended fuel.
Where I have noticed a difference is crappy gas. I stick with Shell, Costco, and Kroger fuel and my 2017 runs great on it with roughly 17mpg on my commute.
Your power ratings listed on the first two were tunes that required premium fuel. The current version of the VK56VD in the Titan is 390hp/394tq in the half ton gasser (I believe to also be the case for the Armada). I believe those numbers are up a tad with the XD.
