I don't think you understand what is HDR , if at all .
Dynamic range is like a canvas . It is measured similarly to contrast , which starts from the deepest black expanding to the brightest peak .
It is what is giving pictures a sense of depth , again similiar to how we measure contrast which play the biggest role in determining picture quality .
Yet under a typical situation , a 500 nits OLED TV will generate the same amount of impact (or "POP" which many of you have heard from HDTV ) as a 1500 nits LCD .
That is because when it comes to dynamic range , the " darker " side of the measurement is far more valued than the brighter end of the spectrum of light .
Human eyes are very sensitive to lights in a way that we are able to perceive more details in a dimmer environment than under strong lights.
A 1500 nits FALD TV probably has a base black floor of around 0.025 cd/m2 , which is roughly equivalent to 1:12000 contrast .
The OLED always starts from 0 , even with a 800 peak brightness it has a typical contrast rating of 1 : 1000000 .
This is due to the flaws coming from the same tech that powers all currently liquid crystal screen , which require a backlight system .
The current backlight system is far from perfection , often requires complex calculation to be functional and pales in real life performance .
The same reason why even these 1000 nits monitor are considered fake HDR advertising . They are just bright screens , there is very little dynamic range on it because they are unable to supress the lights effectively .
You just said you can't afford an OLED , yet you somehow manage to come to this conclusion .
Please don't tell me you are making the judgement from a highly compressed youtube video with an extremely limited dynamic range .
It is physically impossible for this to happen ,
The only circumstance I can think of is you are in a very , very bright room or you are watching large patch of snow field , in which case the strong ambient light is overpowering the screen with glares .
Self emissive screen such as the OLED always gain an advantage and willl trample over the LED LCDs when it comes to sheer picture quality .
And we have not even begin to talk about dark room performance .
In dim / pitch black room , that advantage will translate into infinite contrast . Anything with a darker background will project a sense of image floating in air , conjuring a semi - 3d illusion , a PQ miracle which you have to witness to understand how awesome it is .
Now now , we have not even started to talk about the plethora of Issue such as screen uniformity . uneven screen light distribution which further reduce dynamic range and contrast , "halos" and blooming and backlight leakage .
If we are being frank here , the 2 technology are not in the same running league.
Well, I'm not really that technical into TV. Just on the surface.Dynamic range is like a canvas . It is measured similarly to contrast , which starts from the deepest black expanding to the brightest peak .

I'm not really comparing anything from technical pov. I know there are more to it than just brightness alone but when watching review from tablet (also an oled screen), the immediate difference in brightness and a more saturated color of the Samsung does make the OLED felt naturally color. Just like many of the reviews when comparing apple latest ipad with mini led display vs oled display from Tab S7+. I'm sure there will be more difference when you at the TV in real life but for now, I wont look at something I cant afford.
