Vizio M70-D3 vs Samsung UN70KU6300 Performance
Picture Quality
The picture produced by both of Vizio M70-D3 and Samsung UN70KU6300 looks greatly for their price range. Both of them have the same deep black level and pretty good contrast ratio. The deepest black level reached by UN70KU6300 is 0.018 nits with about 5400:1 of native contrast ratio while M70-D3 reaches about 0.21 nits of black levels with about 4800:1 of native contrast ratio. This value is not far behind what reached by top model HDR TV that available in the market even much deeper than most of TVs that available in the market. With deep black level that reached by them, this should makes dark scenes of the picture that displayed on each of their screen looks sharp and rich in details. Moreover both of them already support HDR 10 where to display fully HDR 10 contents, it requires 0.05 nits or lower of black level. What reached by both of them in term of black level is quite enough to exploit details of dark scenes of the picture so looks more clearly.
But in other hand, both of Samsung UN70KU6300 and Vizio M70-D3 are not including bright TVs. On all % of window, peak brightness that achieved by UN70KU6300 is similar that is about 425 nits of peak brightness. While peak brightness that reached by M70-D3 is about 415 nits on 25% window. On 100% window, peak brightness of M70-D3 even is even dimmer at about 240 nits of peak brightness. What reached by them even is lower than peak brightness which reached by most of LG IPS TVs. For displaying SDR contents in dark room, it might be more than enough, but for displaying SDR contents in bright room, this is still less than what is needed, much less for displaying HDR contents, peak brightness that reached by them certainly is still far from what required. As we know, to display HDR 10 video fully, it need at least 1000nits of peak brightness, even Dolby Vision needs much brighter peak brightness. This course makes the details of the picture on highlighted areas of lights cannot be displayed pretty well. So, if you decide to buy one of these TVs, you should not use this TVs in a bright room or avoid panel from direct light beam.
Moving on color performance, range of color that can be covered by each of them is also not much different. Color delivered by Samsung UN70KU6300 can covers about 83% of DCI P3 color space while color produced by Vizio M70-D3 can cover about 81% of DCI P3 color space. It is good enough to display SDR content which needs Rec.709 color space. But for displaying HDR contents, it is certainly far from what required. As we know, for displaying HDR 10 fully, it requires at least 90% of DCI P3 color space with 10 bit depth of color while Dolby Vision even need much wider color gamut that is Rec.2020 color space with 12 bit depth of color. In term of depth of color, UN60KU6300 supports 10 bit depth of color while M70-D3 supports 8 bit depth of color. You need to know, 10 bit panel can deliver about 1.07 billion shades of color while 8 bit depth of color can deliver about 16 million shades of color. As the result, color gradient of the picture that displayed on the screen of UN70KU6300 looks smoother than what produced by M70-D3.
Additionally both of these Vizio M70-D3 and Samsung UN70KU6300 use VA Panel. As long as you watch TVs from front and center, the picture will look stunningly. But once your viewing angle is wider than 20 degrees off center and front, contrast and color will looks deteriorate. The wider of your viewing angle, the image will be seen deteriorating.
From display specs that offered by Samsung UN70KU6300 and Vizio M70-D3, both of these TVs can have deep black level and pretty good contrast ratio that makes the picture that displayed on each of their screen looks stunningly, especially in a dark room. But both of them are not a bright TV, so quality of the picture will looks less than maximal when they are used in bright room. As well as when they are playing HDR contents, their peak brightness and color gamut are far behind what required for displaying HDR contents fully. But if you don’t care about full HDR performance, what offered by Vizio M70-D3 and Samsung UN70KU6300 is quite enough to satisfy you in enjoying HDR entertainment in your home.

Conclusion
As we have discussed above, although Vizio M70-D3 and Samsung UN70KU6300 offers similar performance in picture quality, but M70-D3 offers slight better picture quality in the narrower area of the images than UN70KU6300. This is due the use of Full Array LED Backlighting with local dimming on the panel of M70-D3 while UN70KU6300 only use direct LED backlighting without local dimming. The other advantage of M70-D3 than UN70KU6300 is about their ability in playing HDR where M70-D3 already support both HDR 10 and Dolby Vision while UN70KU6300 can play HDR 10 only. When handling Motion blur, Vizio M70-D3 is also superior to Samsung UN70KU6300 due the use higher native frequency of refresh rate panel.
In other hand, Samsung UN70KU6300 is superior in term of UHD Up-scaling performance especially when the source is 480p or 730p contents. Additionally, Tizen OS with complete apps is also more attractive than SmartCast that only focus on streaming video, despite frequently used apps of Smart TV is that has to do with video streaming. In term of connectivity, although UN70KU6300 has less HDMI Ports, but its input lag is lower especially at 4K HDR signals and of course it is better for playing HDR Gaming. Additionally, although sound quality both of them is not so impressive, but UN70KU6300 is offers slight better.
So, which is a better between them? As mentioned, with superiority in picture quality and ability in supporting HDR formats, Vizio M70-D3 is sold about $400 more expensive than Samsung UN70KU6300. This certainly comes back to you according to your need and taste. I just try to describe the superiority and inferiority between them while the decision still comes back to you.
