This was interesting to me because so much underwater video is done with artificial lighting. It's very different seeing it native.
I love the HDR on my Apple TV and LG display. The worst part of most modern movies is how much takes place in low light with little to no consideration for how it will look outside of the theater. As a parent and an anti-social person I hate going to theaters. But when I do go, it's clear that these films are made for viewing under conditions most of us can't (or won't) achieve in our home.
