Wanted to post an update:
Got the QR in my hands, finally after it's long trip from Germany to Canada.
I hate speaking too soon, but this panel is utterly fantastic. It came pixel perfect which is lucky as hell because the box was mangled to all hell.
I have a Viewsonic VP2770 beside it (currently the best PLS panel on the market for multimedia/general use/gaming) other than the Korean exports. The PLS panel is quite a bit darker even at equal brightness levels. As far as input lag goes and responsiveness goes, it comes with 5 overdrive levels (0-100 in increments of 20) and I'm using 80 right now, and it's there's no ghosting, at least, no ghosting you'd ever notice. I tested it with Starcraft which is very hard on monitors that overshoot due to the high contrasting colours moving quickly, and I tested it in BF4 test range, which is usually pretty good for finding ghosting and general "slowness" to pixel transitions, and the panel performs better than the VP2770 in my subjective opinion.
All in all, quite pleased with this panel. I love the physical design, and it's taken me ages to find an LCD with the characteristics I want. Who knew I'd find it in an obscure model change only sold in Germany and UK...??
