I dont know if it makes a difference halachicly, but due to the massive difference in what is considered appropriate behavior and not appropriate behavior among genders/sexes (I dont want to offend anyone by misusing either word) between jews and non jews, certain behaviors by a jew will not be viewed as “holy” by a non jew but rather irresponsible and even disrespectful or rude. To a goy, there is nothing “arayos” with calling someone by their own name and is considered rude and disrespectful if you dont use their name in many instances. Use your seichel and when in doubt consult a Rav.
On the topic of calling someone by their name, even some non jews recognize the feeling of “personalness” (for lack of a better word) created when calling someone by their name. Dale Carnegie in his lectures and his books writes how the nicest sounding word in any language to every person, is the sound of their own name. He uses this idea in a number of contexts.
