These are very nice results, generally. Is there any access or advocacy benefit to re-testing now? If not, I would hold off for a few years. His level of testability is not going to increase that much in a few months, and it would be a waste of the 2-year re-test period to test him now with the WISC-V, without a very good reason. I will say that the ceiling on the WPPSI-IV for a high-functioning nearly-six-year-old is fairly low, so this is just a starting point for looking at his areas of cognitive strength.
With regard to advocacy, his results do clearly indicate that he is in the MG range in nonverbal areas (VS and FR), which have implications particularly for mathematical thinking. Given the significantly lower VC and PS (how are his pencil skills?), advancement in first grade may or may not be necessary, as most of first grade is about reading and handwriting. From what you report, it sounds like you have advocates for him in the school, so the incremental benefit from re-testing would probably be negligible. (Since the SP already believes he is brighter than his scores suggest, and there is no GT service gated by a higher score.)
ETA: Went back and read your old posts. I see he is already advanced in reading and math. In that case, he probably will need something in first grade, but the point about already having in-school advocates remains. Did she make instructional or placement recommendations in her report? That might be a good place to start. Handwriting will probably still be a concern, when considering his programming, as he probably is not ready to generate any more written product than his age-peers. So you'll have to be prepared to ask for supplementation or advancement that relies on only limited pencil and paper work.
