So you use it just to display a label NEW in the frontend so users could know that article is new?

Then there is no need to use isNew field at all. You could just use published_at in the frontend, make some calculations like this:

if ( difference ( currentTime - article.published_at ) < 24 hours ) {
  article.isNew = true;
}
