According to CNET: Samsung's official answer is that the S doesn't stand for a specific word. Rather, according to the rep we spoke to, "Samsung reserves the 'S' (in SUHD) identification for their flagship products that change the game, like the groundbreaking 2015 SUHD TV portfolio or their Galaxy S and so on."
So relatively speaking an SUHD demo is nothing more than a UHD demo prefixed with an "S".
Well, I'm not arguing what the S stands for, I'm arguing that there's a difference between UHD and SUHD.
720p is HD, 1080p is Full HD, 4K is Ultra Full HD (UHD for short). But that's just in terms of resolution.
What SUHD TVs bring that's not available in regular UHD is beside the 4K resolution, it has 2 other important components: High Dynamic Range (HDR), and Wide Color Gamut (or what's called Nano Crystal color by Samsung). In TVs that support HDR, like Samsung's SUHD TVs, or LG's OLED TVs, the HDR is possible by a higher contrast capability (black is blacker and white is whiter/brighter). Technically the JS900 is SUHD and has Nano Crystal color and HDR, but it's only edge lit so its HDR is not going to be as good as the JS9500 HDR, which is FALD.
You can have content that's UHD, but that content may not take advantage of imagery that can be supported by HDR and WCG. In that sense, that content looks pretty much the same between a regular UHD or an SUHD or an OLED TV.
If you have content that's not just UHD, but created specifically to show off HDR and WCG capabilities in mind, then you can see the difference when you play that content on an UHD TV vs an SUHD or an OLED TV. Sure, the compatibility is the same and you can play the content in any 4K TV, but the HDR content will look better on an SUHD or OLED TV than a regular UHD TV.
That's why I want to take the trouble to differentiate between regular UHD content and special UHD content that is designed to showcase HDR (and maybe WCG as well). The special UHD content designed to showcase HDR and WCG will look spectacular on an SUHD or OLED TV, and less spectacular on an UHD TV.
The bottom line is that if you take a UHD content and it looks the same on a regular UHD TV vs an SUHD or OLED TV, then I wouldn't call it HDR content. If it looks different between UHD vs SUHD or OLED, then I would call it HDR content. And how would we know? Unless we can compare the content side by side on a UHD TV and an SUHD TV. Or unless the content maker specifically label it as HDR content to tell us that they have created it with HDR in mind, and you need a TV that supports HDR for the best viewing experience.
