I would think that the heliosphere would also distort the stars positions somewhat like the atmosphere of the earth does.

Given that we measure the distance to stars using parallax from our own opposing positions in solar orbit, 186 million miles apart from each other:
then I don't see why it can't be observed from observations taken 4 billion miles apart?
Here's where the video got the story:
