I have no idea what the reset panel blacks look like, but I remember seeing some test patterns with a D-Nice tweaked 500m ( mll was maybe .0003 ftL) next to an LG OLED (may have been the EC9300). I think it was the 2014 shootout and from what I can remember, the difference was marginal at best and this was before LG was even close to getting shadow detail right.
I haven't been to one of Robert's events in a while, but it seems the OLED is winning HDR because of deeper blacks, despite getting half as bright as the LCDs. Anyway, it's that feature that has me really considering upgrading to an 8 series LG this year, but I am still blown away by movies on my Kuro. Even streaming looks great most of the time.
