There is no such thing as an English Cream Golden Retriever, Exotic Red Golden Retrievers, Platinum Blonde Golden Retrievers or any other kind. There is only one breed of Golden Retriever and they are all some shade of gold. There are however different styles. There is Field Bred, Show Bred, and European Bred.
The field bred Goldens tend to be a lot more athletic & energetic, have shorter darker colored hair, longer legs, and are just a little smaller all around. They are the ones that sometimes get mistaken for Irish Setters. They don't usually do real well in conformation shows because they are bred for hunting, but they are usually really good at agility and obedience.
The show bred Goldens tend to have longer golden hair, a little shorter legs, and a are more stocky than the field goldens. You usually see this type on TV. They do well in conformation shows because that is what they are bred for. They are usually really good at obedience, agility and rally.
The European bred Goldens can be like both the field and show bred. They are just bred to the European breed standard, most of them are very light golden in color and they tend to be more stocky. However, they differ a little from their red/golden-colored counterparts in the temperament category. While all shades are known for being friendly and good-natured, the "cream" or "white" Goldens tend to be more “laid back”. They are also good at obedience, and rally.
The field bred goldens can be light colored and blocky, the English bred can be lean and darker colored, and show bred can look like both, this is just an example of what some breeders breed. Everyone has a little different preference.
So whenever someone says English Cream, Exotic Red, or Platinum Blonde Golden Retriever they are usually just referring to color and/or style, not the breed itself. Your AKC registration papers will only say Golden Retriever.
