If it's worth it is entirely up to you. That said, I think there are many instances in the movie where I was awe-struck at the UHD presentation. The flashback scenes particularly looked especially striking. Even some of the dimly lit sequences were quite impressive. This is now in my top 10 for overall UHD presentations.
