You said “Tvs like x95j are a dying breed” and “people want mini led.”Well you're response was telling me that mini LED is used with FALD. As if I didn't know that, so I'm not sure what you were thinking.
At this point I have no idea what you're talking about zones for. The point I made was that there is little appeal for most people in the X95J. Its too expensive for what it delivers. Sony themselves said that they couldn't offer a 55" X95J due to how low it would need to be priced, and because 55" OLEDs can be had at that same price range and are much better, it wouldn't sell. So don't be surprised if they just kill that model off entirely this year. The point of the X90J/K is to have a ~ $1000 55-65" 4K TV that can have decent mass appeal. Fairly cheap to make, good enough picture quality, and significantly less expensive than their A80J 4K OLED. Most people who are looking to drop $1500-$2500 on a 55"-65" 4K TV will just get a LG C1 or Sony A80J. The ideal of the X95, a high end 4K LCD that's similar in price to the A80J, a mid range 4K OLED, is becoming less and less appealing. Too expensive / not good enough.
My response was to say the whole point of mini led is simply more dimming zones, so just having mini led doesn’t automatically make traditional fald displays obsolete. You can achieve the same result as mini led with just more dimming zones.
As a matter of fact it’s possible for a traditional fald to beat mini led depending on the implementation but of course a balls to the wall mini led from Sony with as high zone count as possible would be best, but then it becomes a cost to manufacture issue, and QA issue…
With mini led, the tvs are usually thinner which leads to more possible uniformity issues and also more heat i.e. less peak brightness. Of course a mini led tv with great QA and a thick body would solve that issue but the trend is thinner tvs.
TLDR there is not necessarily a benefit to mini led technology as of right now.
