Since you mentioned Rtings - Rtings says the following about the Samsung KS8000 and Vizio P Series for contrast and peak brightness:
Black: 0.016 cd/m2 White: 110.5 cd/m2
Contrast: 6906 : 1
Very deep blacks and remarkable native contrast ratio results in a rich picture quality.
8.1 Peak Brightness
Peak 2% Window: 1472 cd/m2
Peak 10% Window: 1431 cd/m2
Peak 25% Window: 964 cd/m2
Peak 50% Window: 513 cd/m2
Peak 100% Window: 509 cd/m2
Sustained 2% Window: 505 cd/m2
Sustained 10% Window: 508 cd/m2
Sustained 25% Window: 509 cd/m2
Sustained 50% Window: 513 cd/m2
Sustained 100% Window: 510 cd/m2
Like for other TVs, we use the local dimming setting ('Smart LED') that brighten the 2% window the most, in that case 'High'. The peak brightness of small highlights is very high at 1472 cd/m². On a static image, the maximum brightness drops to around 500 cd/m². For the best HDR experience, leave 'Smart LED' to 'High'.
Vizio P Series
Black: 0.018 cd/m2 White: 102.5 cd/m2
Contrast: 5694 : 1
Excellent native contrast ratio. The blacks are very deep, even when local dimming is off.
7.2 Peak Brightness
Peak 2% Window: 335 cd/m2
Peak 10% Window: 466 cd/m2
Peak 25% Window: 518 cd/m2
Peak 50% Window: 555 cd/m2
Peak 100% Window: 567 cd/m2
Sustained 2% Window: 335 cd/m2
Sustained 10% Window: 466 cd/m2
Sustained 25% Window: 518 cd/m2
Sustained 50% Window: 555 cd/m2
Sustained 100% Window: 567 cd/m2
This TV cannot get a small highlight as bright as other high end TVs like the Samsung KS9500
or the Sony X930D
; but it can get very bright across the entire screen. Bright scenes should perform well compared to most other HDR TVs.
So the Samsung wins in contrast and peak brightness, the Vizio in sustained brightness as I had said. But nobody is turning up the brightness all the way anyway, especially in a dark room. I can't see how a sustained brightness of 500 nits across the entire screen would not be bright enough for you. Why do you feel you need so much brightness in a dark room? Typically you can use more brightness in a very bright room.
And regarding FALD, while that is certainly preferable over edge lit, I really don't think Vizio's have enough zones with just 126 or 128 vs. the 600 in the Sony 940D. Rtings comment about the Vizio's FALD follows:
"The local dimming feature on the Vizio P Series 2016, called 'Active LED Zones,' works really well, thanks to the full-array backlight. In our video, the white dot is a bit dimmed, which is unfortunate, but at least there isn't any major blooming. You will see more blooming at an angle than you will from directly in front of the TV. When watching movies, a downside of this feature is that stars in the sky won't be bright, but at least the blacks will be great."
Since the FALD actually dims bright objects, isn't that going to cancel out that extra brightness in dark scenes? And it is the opposite of what is supposed to happen for HDR.
The bottom line is they are both excellent for movies, the Vizio falls down in upscaling lower resolutions such as cable TV, but it excels in gaming with its inherent low input lag.
