It could be said that Jon has Valyrian blood but does not practice their culture. Having been raised in the North, Jon is more of a Northman.

This discussion reminds me a little bit of those with different national descent. An example being Italians who emigrated to America in the early and mid 20th century, their children who are born in America, grandchildren and great grandchildren are considered Americans with Italian descent, so while they have Italian descent, they are not Italians.
