The page https://en.wikipedia.org/wiki/Basilica_of_Saint-Denis states

> Although known as the "Basilica of St Denis", the cathedral has not been granted the title of Minor Basilica by the Vatican.

Does it matter when it has been called like that for more than 12 centuries?

Well there's a lot of people with the family name King, but you know, they still have to play (and win!) the fancy hat game to be actually granted royal rights.

In that case it is different because it is/was a building used by the french church. Not some random one named like this by someone with no relation to the church.
