I replaced my center caps just like yours that came in a Porsche Tequipment box like this, but I went with a black and silver crest instead of the colored version. They don't have that second ring like the original center caps, but they fit perfect, no gap. I bought them back in 2016 and they are as snug today as they day I bought them and zero fading. Maybe return them and look for Porsche Tequipment center caps. I got them off eBay brand new also and I don't remember the price,but it wasn't bad, pretty sure they were under $100 and I got them from a person selling them and I think he was just looking for a quick sale.
