Dual-LCD displays are extremely inefficient, as each LCD layer absorbs 75%-90% of the light even when it's fully open due to the use of polarizers.
Mostly as a result of that, they are also heavy, noisy (active cooling due to running very hot), and have significantly reduced viewing angles, since the stacked LCD arrangement doesn't work as designed when you go off angle.
In exchange you get... The ability to stuff an even more powerful backlight in? There's virtually no limit to how bright you can make a LED backplane, 100K nits if you want to, it's only limited by power and cooling. And that's all.
If you are a professional, you are grading content that will be viewed 10, 20, 30 years later. The original Star Wars has hit 42. In 40 years, displays will have much better peak brightness, and if you screw up now, it will be a bit late to fix it. So you need the ability to cover as much brightness range as possible.
Since you are working alone, and on a fairly small screen (as you aren't there for the immersion) you don't care for the viewing angles. Since there is no sound yet, you can use headphones or other music, and the display can be fitted flush inside a wall anyway. And since it's all owned by the studio, you have no idea or care for its weight and cost.
This is a narrow, specialist set of requirements, in gross disconnect from what people want to see in their homes.
Dual-layer LCD have been known for decades. There was no breakthrough in the field. The only reason they're coming out now is the need to grade future-proof content in luminance ranges beyond the ability of native HDR displays.
Micro-LED is a similarly bulky but much less visually-compromised technology for extremely large screens. But the cost isn't coming down much - it can't, while they still have to be built up pixel by pixel - and you still need a very large display to pull off at least 4K. Very few people who don't own a company and aren't paid in FAANG stocks will be able to afford a home large enough for one, never mind the screen itself costing like a home.
If our economy suddenly turned into in a Star Trek world, where room size is still limited, but any appliances can be automagically fabricated if there is a standard design, I'd still bet for the 8Z88 getting far more orders than the BVM-X310, Dolby Pulsar, and The Wall combined. On the sum of its characteristics, it's a better TV - lighter, thinner, better looking, sized for real home rooms, with perfect blacks, and bright enough for any practical viewing, unless you're trying to fight the Sun. There would even be more orders for each of the Q90 and the Z9G than for the three exotics. Assuming the fabricator isn't banned from making window blinds!
