Welcome!
If you browse through the Twice Exceptional forum, you will find numerous references to children with this kind of diversity in their cognitive profiles. Even if it is does not appear to drive educational challenges in your child, you may find some of the conversations to be valuable. And while it certainly isn't destiny, I would also not be too quick to assume that this will not become an area of challenge at some point in the future, especially in a relatively young child. In particular, I would keep my eye on secondary-level mathematics (geometry is a frequent trouble spot).
Generally speaking, in a child from a reasonably enriched background (adequate health/nutrition, books, toys, play, healthy relationships with adults and children), there is no particular expectation that the cognitive skills assessed by the PRI (or any other academic cognitive skills) can be "improved" by training. To date, there is no rigorous research showing that any kind of braintraining or intervention can raise cognitive ability beyond those benefits accruing from a healthy, nurturing environment.
