If you are not going to use the new features in the 6S phones, why do you need to upgrade?
The way you put it, the 6 is serving you just fine.
Everyone knows the S upgrades are more under the hood than the overall aesthetics of the phone.
I upgrade my phone on launch day without fail for the past 6 years or so.
There are features which we use less in the S upgrades like Siri, but the Touch ID was the most successful feature in all the S upgrades ever, in fact it brought about an industry wide need for fingerprint unlocking on mobile phones. Not to undermine the fact that Siri brought about the need of Digital Assistants on phones like never before.
As far as the 4k video is concerned, prices of 4k TVs have dropped tremendously over the years. Its becoming easier for people to afford 4k TVs now. 4k is becoming a norm if it already isn't.
1. It's not our call or to decide for people how they use their phones for

It is for the same reason that I would not question something you have bought which you feel is really useful while I feel is completely rubbish or otherwise

That's your choice to buy and decide, it's a free country. If someone wants to buy an iPad and use it as a digital photo frame, that's up to them too.
2. I am talking based on real statistics and data. Having cheaper 4K TV's does not mean a higher 4K adoption. If you go by that assumption and if you are a marketeer, you would probably crash hard. You can easily ask any manufacturers or sellers be it TV's or PC LCD's, I can pretty much tell you that 4K screen sales are still minimal compared to other resolutions.
3. That said, if you own an electrical shop, do you think it makes sense to stock and display more 4K screens on demo compared to normal non 4K screens? If your answer is "YES" then almost everyone in the business is making wrong decisions.
4. Not all sources are 4K ready. I had a 4K LCD on my PC, a lot of the videos, movies, etc doesn't look good on the 4K screen. Font scaling is also another issue on the Windows platform.
5. I value your experience in 4K and I am one of the early adopters as well. However, I do not think it's a fair comment to generalize and think this is the trend just because we have a 4K screen

The jump from Full HD to WQHD takes a bit of time and there's no difference with this phenomena either (4K)
