I'm not exactly sure what is the reason behind it, but I'm certain there is a difference, especially some of the early A359 deliveries.

I've seen some people write about the technical differences here, which is not my cup of tea.

I'm also not sure what if anything is being done about this, and maybe it is being rectified.

It is possible to get on one of the "bad wifi" A359s with a full load (I think it was B-LRD? Or maybe LRF or LRA?), and have borderline unusable internet for the entire flight. Pretty much useless. I had this happen from SFO a few months ago.
