SW might have been disproven, but in this case, I think it would make a difference. I think if you had to have 4D vision rather than 3D, it would require much more processing power and memory to account for the extra dimension. So I think at minimum, a being that is capable of thinking in 4D would have to have higher brain capacity than a being that thinks just in 3D. And there is some strong evidence that our ability to navigate 3D world influences our general cognitive capabilities.
