EIZO is definitely great, but 4K EIZO screens ain't exactly cheap either. Closest to consumer-level are the CG248-4K and CG318-4K (which actually are reference-grade) and cost about $2,800.
Ah, I totally forgot about Flexscan. They're definitely more suitable for consumer than ColorEdge. I think I didn't considered it because it doesn't have DCI-P3, but it is definitely a great monitor.
