Answer is simple, the technology is not originally from Sony. (How Sony name it - yes).
You should know, manufacturer like Sony, Panasonic does not make their own panel anymore.
Even for LG or Samsung. Not all series of TV used panel manufacture by there own. If you dont believe it, open up the TV and check it.
All you are paying is the brand name.
I find your comments really patronising. I'm no expert but I'm pretty sure I've better knowledge then you on this topic.
My sony uses a rarer 240Hz PSA panel that is similar to PVA, I doubt it's from Samsung. Even Samsung doesn't always manufacture it's own panels. My previous Samsung uses panels from AUO. They outsource because they choose to focus on other aspects of the technology.
But that's besides the point.
The panel type and quality is important. But it isn't everything.
Case in point - LG supplies oled panels to it's competitors including Sony.But after you factor in Sony's technology in video processing, the resultant product that Sony produces using LG's panels could be superior to LG's own flagship offerings.
Regardless, I suggest you take the marketing hype with a pinch of salt.
The reason why samsung pushes the so called "Qled", is obvious to anyone following display technology over the last few years.
Samsung lost the oled war, as it could not bring its oled manufacturing technology to match the yield of LG's. Given the rivalry with LG, Samsung is obviously reluctant to procure LG's oled panels. Without its own oled panels, Samsung had no choice but to repackage existing quantum dot led/lcd technology, and market this as something that is oled sounding, hence qled.
Samsung obviously hopes that the unassuming consumer will get confused, and start to think that qled is something that could be 'equivalent' to LG's oled. If samsung had continued to sell its TVs as just plain old LEDs, they might lose market share, and perhaps more importantly, deal with the embarrassment of not having it's own self-emissive panel TV.
But surely we should know better. Can led/lcd panels, with or without quantum dots, produce a good picture? Obviously there are still some benefits - no burn-in, higher levels of brightness exceeding 1,000 nits giving more headroom to handle HDR without a need for tone mapping, and so on. But ultimately, to achieve comparable contrasts without sacrificing details, you need a high zone count FALD, like Sony's ZD9. Can samsung match up? Yes, if it stops fooling around with its HDR eotf, and increase its dimming zones on its led TVs, coupled with its non-reflective technology + newly achieved wider viewing angles, perhaps. But until then, Sony to me, is still king when it comes to led/lcd TVs.
