In Boost for reddit, it was visible right away, without any clicking. It was incredibly convenient. I'd very much like to see this feature too.

Yes, that information, but without having to long press. If it's displayed along with the post title, I can quickly see where it goes and skip to the next post if it's clearly a video. Otherwise, I have to read the title, decide if I'm interested in it, then do a long press, possibly to be disappointed by what I see.
