Is your current machine a Retina 5K 5120x2880 P3 display?I'm not sure! I've maxed out on a BTO 5k iMac nearly 3 weeks ago and it has the exact same specs as Apples website is displaying in terms of GPU/CPU etc. However there is a subtle difference - the screen is now being described as "Retina 5K 5120x2880 P3 display". I'm sure it didnt say this when I bought mine. Is this what you are referring to?

Yes it is deffo a Retina 5K iMac (just checked my invoice!) but it doesn't specify what the actual screen is, it just says "27-inch iMac with Retina 5K display".
Maybe Apple have decided to elaborate a little bit more on the type of displays being used??
