The original (wild type) coloration is black and white, but domestication has produced many more colors, including white, black, chocolate,blue.
So wild type is based on colour but also here it refers to size wild type muscovys are seen as small birds that fly well and perch.Over the years we have produced birds that are bigger ,more pronounced faces.Very stocky in legs ,lower to the ground.
Others may have different opinions of this but the muscovys we are seeing today have little apptitudes to the original species.This is just the way they are evolving.
The meat market wants big birds so that is what they are getting.
Showing "wild type "muscovys whether you are concentrating on colour /size you need to be a brave person or maybe like me a few screws short

The show circuit does not look well on small birds the only area you really can play in is colour but you will not be able to win over a bigger/stronger bird and that is the fact

And thats my five cents worth will be interested in what others have to say.
