You're correct. I mixed up the first sentence with the next.

But it seems to be an IPS, of some sort:

"The P2815Q packs an IPS LED display will have a full 3840 x 2160 4K resolution. It launches globally on January 23. Dell hasn’t yet discussed things like refresh rate or range of inputs (I’m sure DisplayPort is a given), but they do promise the same “screen performance” as the new UltraSharp 32 and UltraSharp 24 Ultra HD monitors. That’s certainly encouraging since their UltraSharp line is normally a cut above when it comes to professional displays."
