Looks like UE4 is coming to UWP and HoloLens after all!

The slide refers to Unreal Engine 4 supporting DirectX 12, which we wholeheartedly do. However, we’re not supporting UWP.

Epic’s position is that we’d happily support UWP if Microsoft made a long-term commitment to keeping it open on PC, in some specific technical ways outlined here: Epic's Tim Sweeney: Here's how to keep Windows an open platform | VentureBeat. Microsoft has actually implemented many of these features since Windows 10 ship, as demonstrated here: Shows | Microsoft Learn.

The lack of clear future commitment is the only significant roadblock remaining. A commitment is especially important because Windows 10’s new forced-update policy enables Microsoft to change the rules at any time. It would be unreasonable for developers to invest in writing software for UWP on the expectation that it’s going to be open, and then suddenly find that a Windows forced-update has locked everyone into Microsoft’s store, services, or some yet-undisclosed certification requirements in the future.

In other words: Before we decide to play this game, we need to know what the rules are, and that the rules won’t change mid-game.

Very reasonable thing to ask for in my book. Especially considering the investment that MS is asking developers for.
