That's definitely not all it can do. Foliage without pop in and into Nanite is cool, but Nanite still has work to be done on (AFAIK you still cannot deform and animate Nanite assets). Lumen advances to get translucent materials working is massive. Large worlds is super cool. And I can't remember if it's in 5.1 in beta, but it brings a new layering model for complex materials that works better than clear coat (which is the current 2-layer model, like a car with blue paint and a protective layer on top) with many more possibilities. Putting those abilities into the hands of anyone is a massive thing (well, putting all of UE5). I've seen firsthand people with absolutely no experience in gamedev but in other media production get up to speed with building environments in less than a week, complete with animations & all. Making small virtual worlds is available to basically anyone. And yes, the author of the video has a target audience of people who already use Unreal Engine. To these people, 5.1 is pretty damn massive.
