I have been following this thread with interest because I have a somewhat similar DD6. She has very unusual VS and VCI scores. I, too, was initially surprised, but the more I have learned, the more I see. I don't exactly know how to label her either. This isn't that big of a deal because I don't go around discussing it with people. But as you say, it's still nice to know what to expect and what kind of reading may be applicable. Ultimately, I've read that this is at least partly a clinical determination, so if your tester used the PG label, I'd say s/he knows your kid better than any of us. Ours didn't give us much more info than scores and the advice that she was going to need a lot more at school.
I think one of the most important things you said was that your DS is well adjusted and has found a good school situation. That's excellent, and I'm jealous! Testing did help me understand a big part of why we've been in three different schools already and has given me more moral support in advocating for her needs.
I hope you continue to do well on this journey and know that while uncommon, you are not alone
