I've been told that any crown not attached to the ridge is called an Angel Kiss.
According to several RRCUS (well-known) breeders this should not be a problem in showing.
That aside...IMO, if I purchase
or sell a show potential dog - I
expect that the puppy be within the Standard of the Breed.
If you do not know what the Breed Standard is...check out the forum on this topic.
If you plan to show the puppy then YOU owe it to yourself to read and understand what it means in relationship to the puppy that YOU purchased.
You mentioned that the breeder is also a show judge - you need to discuss the Disqualifications, Undesirable Traits and Faults as they pertain to your puppy.
You will be a novice at showing and as such, it will be a struggle to learn the correct way to showcase your dog in the ring. Not a problem with the right training/mentoring...and working on this daily. We all began as a Novice.
I wonder why you would consider breeding a dog who may have Disqualifications, Undesirable Traits and/or Faults. Even ethical, excellent, longtime breeders strive to use the best possible dog for their breeding programs.
There is nothing at all wrong with choosing the puppy that tugs at your heart.

But while it isn't impossible,
it isn't easy to compete as a new owner and having the best looking puppy in the ring can certainly be a plus.
If the breeder required a show contract they expect you to abide by that contract and the majority of breeders are willing to spend additional mentoring to assist their show buyers accomplish that.
Each country has a breed standard...some are slightly different.
Each country has a 'style' that may vary in appearance.
Every country has their unique way of presenting a dog in the ring.
However, it's best to buy, or breed to the dogs that best fit the Standard. JMO.
People who are new to show dogs, contracts, standards and breeding sometimes take offense to breeder contracts. But there IS a reason, particularly if the breeder is selling to a novice, first timer. Keep the line of communication open between you and your breeder - and really listen to them. You may not agree with all they say 10 years from now...but if you listen - you will learn much to assist you along the way.
Good luck in all you plan to do...but most of all with your relationship with your puppy.
This is the beginning of a beautiful time that all too soon ends.
