I bought and returned this display. The panel I got was practically unusable if you have even just a little care for color. All four corners were significantly dimmer than the center, and color accuracy dropped off toward the bottom of the screen. Somehow the macOS dock icons were washed-out and dim.
Unfortunately, this seems to be a common issue with this display, not a one-off panel discrepancy.
Do yourself a favor and wait for whatever Apple has upcoming, at least if you’re in the Apple ecosystem already.
Relay is basically the framework that brings everything together. Relay handles data fetching, storage, and mutations using a central store and GraphQL. If I'm understanding it correctly, Redux is replaced by Relay.
