Nature's Fury is derived from "Core Universe" but they are not the same. (Core Universe is longer). Until recently on the Dolby Access app, there was a video called "See Hear Spectacular" that showed off the black levels on OLEDs in addition to Dolby Atmos. It was by far my favorite demo and they removed it during the December update to the app for some inexplicable reason.
It was basically the same as "Core Universe" and I have been looking for it myself for months. The only way I know to really get it is on the 2018 UHD Dolby Demo disc which is not sold but given to demonstrators. It occasionally pops up on ebay. I've been tempted to get it a few times.
