The Apple's display is not a dual stacked LCD.
Dual LCD is not all that new a tech, and has been used for very niche, usually one-off, HDR displays, before OLED and even FALD. But dual LCD is incompatible with wide viewing angles. Early ones required spot on viewing from some distance; newer ones (or really just the one) do without.
Apple's native contrast ratio is not stated, but it's likely to be in the range of 1,000:1 to 2,000:1 as has been achieved by other IPS. Since they're relying on FALD for contrast, they've got little reason to go after native contrast, as it's often a tradeoff vs viewing angles.
Since 576 is about as many zones as the best high-end FALD, and considering that monitors are usually viewed much closer up than TVs, the results would be expected at the upper end of that range. Perhaps Apple has done much better in FALD controller design. Also, monitor comparisons conditions still use a lot more ambient light and smaller viewing angles than TVs.
In any case, computer monitors, even professional ones, have been stuck in the low-brightness, low-contrast, barely-SDR world for so long that this is a breakthrough for them. Tiny-screen 8K wasn't, and FALD has been long delayed on PC monitors out of fear of producing an inaccurate image. Perhaps this validation will help it along.
