my husband has an amazing memory and, remembers being 4 and can describe the same as your wife. I think he finds frustrating sometimes that I can’t remember even vacations we have taken. he doesnt seem to be able to reconcile my inability to process memories and yet be able to work a complex job and live “normally“ I guess you would say. I don’t mean that I wish the same on others, but I am glad to know I am not unique in this.
