*VA (PVA, MVA) monitors
Many of them are able to show accurate colors and deeper black when left with a colorimeter "one-to-one". But this is "technical" black.
In fact, *VA monitors suffer from angle issues too.
This time it's horizontal color shifting. Two components of the issue are: loss of dark details from the front view and quick increase in brightness of black (=CR drops) from angle view, especially from diagonal view.
Below:
*VA Colorshift Diagram is supplemented with angle view comparison taken from prad.de tests (one of expensive Eizos on PVA).
A famous test photo on the NEC 2490 and the Eizo CG241(PVA).
Some darker details (the bottom parts of turtles) are lost on PVA. They reappear from angle view, but note: all turtles look different that is false (all three are identical).
The NEC 2490 vs 27" PVA (WG). Although "technical" black is blacker and CR higher on this PVA, the movie scene looks washed out. Note: so-called "deeper colors" of WG are eaten by angle colorshift.
