aura of art-house taste - meaning?

[Kamila M]

How could I paraphrase the expression in bold. Please help.

Once you watch a few of these films, the attraction becomes clear: unlike Bergman's often arty, ponderous parables, modern Scandinavian movies are brilliant at telling universally recognizable stories without sacrificing an aura of art-house good taste.

My nonprofessional sentiments:
while retaining the charm of foreign art films.

without pandering to the mainstream
