I honestly think we [defined: public at large & manufacturers, not the calibration crew here] have gone nuts with this rampant promotion and obsession with darker than dark black levels.
Uber dark black levels are not "good" black levels, they're just Uber dark black levels. What I want are black levels that aren't part of a luminance curve that takes everything from dark brown and dark or very dark gray or black and squashes it down to a visual rip in space time. And even if you're lucky enough to get something that moves ONLY recognizably black objects to this super black, it still is overboard IMO.
Hyperbole aside, I look at some of these panels and realize that the black levels they're displaying only appear in nature on the panels themselves.
