Netflix L4 to L5 promo

Now that it's been over a year since levels were introduced at Netflix, what have been people's observations or experience with promos at Netflix? Specifically, how are L4 to L5 promos? What are expectations? I saw this from a year ago, but at that point it had only been around half a year since levels were introduced (correct me if I'm wrong) - https://www.teamblind.com/post/Promo-from-L4-to-L5-at-Netflix-xyFSZDVu offer: 360k
