I honestly don't think so, because it's for the sake of continuity, as Jack Horner, the first major paleontological consultor of the series, in an article I found where he was interviewed regarding some of the film dinos, puts it. They wouldn't really retcon things so much to the biggest of ways just to show people "This is right and wrong and where's why!" kind of thinking you might find online. And this game, like the previous one, focuses heavily on authenticity of the Jurassic franchise, so I wouldn't be surprised at all if it was given the JPIII depiction.
Besides, when Horner was interviewed by Jurassic Outpost in 2017, he said they made it like that because it was the best they could make it to look accurate at the time. Nowadays, he says it didn't really look like that, but based on what he said in regards to the rex's hand pronation in the said article I found, it and everything else (for the most part), likely including the JPIII Spino depiction, is for the sake of continuity unless given a proper explanation. And that kind of "continuity" thing has even carried on with the dinos in the 65 million year flashback of Dominion's extended preview, in which the featured dinos from earlier movies, don't look, act, or sound any different from their modern resurrected counterparts at all. The only exception I noticed is the Rex's fluffy top half which somewhat plays along with something on a viral website's piece of lore info, something I think might be explored further more in Dominion.
To Horner and some of the more reasonable professional/expert and veteran paleontologists, the ultimate gain from the films isn't the accuracy of the animals, but the general interest of the animals to the audience to expand the pool of potential future paleontologist jobs.
