Hi and Welcome!
It is too soon to tell. What does your breeder say about this? I'm unable to copy this information from the breeder site I found it on but they state that the pigmentation may start to darken within a few days, or it may stay pink.
Will the breeder let you change pups with someone else? That seems a bit unusual, especially if the breeder helped you to select the pup with the temperament you were hoping for.
I can tell you too, that even if your pup's nose turns quite dark, it may fade again as they get older. This is usually called snow nose or winter nose. Just as tanned skin will fade without continued exposure, so can a puppy's nose.
This is the transformation of my cream boys nose.
This is what he's settled into. His eyes kept the dark lining and his nose is dark at the fur but is a medium brown out to the end. With fading colors like red, apricot, cream, brown, really almost every poodle color, it's always interesting to see the changes that might come.
