How about Apple switching to a VA-panel in their next iMac? Much better black levels. Improvements are incoming for VA-panels, see link below. The iMac would get oled-like viewing angles and great colors if a QDCC was incorporated as well, but that requires an in-cell polarizer. Is Apple using an in-cell polarizer and a QDCC in their new XDR-display?


Advanced liquid crystal displays with supreme image qualities



5. Conclusion

We have reviewed recent progress on liquid crystal displays from three key display metrics: fast response time, wide colour gamut, and high contrast ratio, which affect the final-perceived image quality. Firstly, we investigate how response time affects the motion blur, and then discover the 2-ms rule. With ultra-low viscosity material, advanced structure design, and new operation mode, LCDs with comparable MPRT to OLED displays can be realized. Next, we propose a novel backlight configuration to improve an LCD’s colour gamut. A functional reflective polarizer (FRP) is working with a patterned half-wave plate to suppress the crosstalk between blue and green/red lights. In experiment, 97.3% Rec. 2020 in CIE 1976 colour space is achieved, which is approaching the colour gamut of a laser projector. Finally, to enhance an LCD’s contrast ratio, a novel device configuration is proposed by adding an in-cell polarizer between LC layer and colour filter array. The CR of a VA LCD is improved from 5000:1 to 20,000:1. To enlarge CR to 1,000,000:1, local dimming backlight could be implemented. Along with other outstanding features, like high peak brightness, high-resolution density, long lifetime, and low cost, LCD would continue to maintain its dominance in the foreseeable future.

I didn’t see anything in the link about OLED-like viewing angles, not even increasing it to IPS levels. I went from a Sony TV with a VA LCD panel to a Panasonic OLED. The viewing angles are vastly different. The Sony was great in many ways, but the viewing angles were worse than a much cheaper Toshiba IPS in another room.

Viewing angles are very important on a monitor because sitting close to the screen means viewing different parts of the screen at different angles. If the viewing angle is poor, any head movement can cause parts of the screen to change massively. VA as it stands is a worse choice than IPS because of this. The article looks to strengthen what is currently VA’s strongest areas, not lessen weaknesses.

It would be nice to see viable VA panels for the iMac, but I don’t think it is likely.

Sorry. They did not talk about QDCC in that article. The oled-like viewing angles comes from having the emitting layer (QDCC) out in front. You can listen to Nanosys CEO Jason Hartlove talking about that in this interview: QDCC at 23:30.
