I see back light bleed in one of your photos, and if appropriate images where used, along with correct camera expose, DSE likely would be visible as well.
It may be good by LCD standards, but thats not a high standard.
The problem is forum discussions end up in absolutes. While the numbers-measurements dont lie, how people perceive a given level of performance can vary wildly depending on their experience. What's great to one person is ordinary to another.
I dont need to waste my time going to see one, I know what that sort of native contrast looks like. Its an LCD with all the well known limitations that imposes, no getting around that.
I high end Plasma has a VASTLY higher native contrast and a native black level over around 10 times lower than your LCD according to measurements. Sony cant just wave a magic wand and make LCD's limitations go away, they are inherent to LCD technology. Then there is the dynamic dimming thing that obviously doesn't bother you, it DOES bother others.
I find high end Plasma blacks marginal in a dark room, not good enough to satisfy me. A high end projector has a black lever around 10 times lower then the Plasma (around 100 times lower than your LCD) AND THAT'S STILL NOT BLACK.
OLED has infinity blacks and contrast, which is in a totally different league to LCD. Main problem for OLED is very limited size, and that IS a problem as far as I am concerned. 65" just doesn't cut it.
i suggest you blokes do a bit more reading before commenting on something you have no experience in, especially you, IviewHD
While OLED TVs produce inkwell blacks and beautiful contrast, those lower-priced LCD sets have an advantage when it comes to HDR. They use high-powered LED backlighting to boost the brightness and the color gamut of the picture. That means brighter fireballs, more-realistic spectral highlights, and more-nuanced gradations between colors.
