I saw i paper a long time ago of a stenography quite resistant to transformations so the basic information was still extractable from the picture. Still i think that a photograph of the monitor would remove it.

EDIT: Even a photo filter might not succeed if it did a homogenous effect across the pixels.

I have to find that algorithm someday.

Knowing BuzzFeed, they would probably just apply a photo filter and call it a day.
