It's just marketing, if you know and understand it then ignore it.
It's just like food shopping, most supermarkets have a food range labelled as 'De Luxe' and they charge double the price for it, over their normal range. It may or may not be better tasting, heathier, better ingredients, of course it could just be a prettier picture on the front.
There are plenty of other things on a profile that would cause me more concern than the use of the word Courtesan.
