Honestly, while I'm one of the people who does this a lot, I don't think it always benefits me. I don't watch 'TV', just streamed stuff but I rarely bother to pause it when I look up these details. And that absolutely impacts my viewing experience because if a movie is plot-heavy enough, I can miss chunks of it easily why I try to figure out why that actress in a minor part seems familiar or what the song playing in the background is. Would love to kick the habit but it's surprisingly tough!
