This post in no way is a judgment on any others, it is my humble opinion after careful consideration regarding any "personalization" of an otherwise gorgeous and, yes this is an exotic car.
After I stated I would not even advertise my son's college via a window sticker, I do believe that a personalized plate is an acceptable means to add some sort of "touch" to make the car your own special statement. That said, even certain plates may be viewed as abnoxious...ie SPSESQ, DRJONES, etc...(these just ask for someone to key your doors...>

I look at it like a speech a senior partner gave when I started my career in one of those large firms in New York. "You may only wear Blue, Black or Grey suits, blue or white shirts. No brown suits allowed, no colored shirts either, however you may wear any colored tie you wish..." I added a little flair with the Jerry Garcia ties....
So to add that certain "touch" I went with an homage to my favorite player on my favorite team...
I feel it is not pretentious, it honors a past personal sports idol of my youth and, no one will think its an arrogant sign of "look what I got" Only I will not drive it to Boston
