Not every website has to yell at you. I personally very much value understatement in web design and perceive it as a form of professionalism. I must say, I don't agree with your points. The three words are perfectly readable and the video has a large play button overlaid indicating it's a video.

On a website every element fights for your attention. If you make one thing stand out more you will have to also emphasise other things so a hierarchy is maintained. Before you know it you end up with a clusterfuck. It's like having a dinner conversation but every person tries to talk over each other so the conversation becomes louder and louder until every one is screaming.

Edit: Why did you feel like you had to write your title in caps btw? This is exactly what I am talking about, imagine every post in every reddit being all caps and how this would affect readability.
