Few TV questions

Hi all,

This is my first post so not sure where to write this post.

I have a few questions out of curiosity.

I see that smart tv are the craze now. I know that LED TV is actually LCD TV just with a LED backlight.

Questions :

1) why are processors never posted on TV website like Samasung smart TV for example?

2) will future TV use HBM memory for higher efficiency to use less power or LPDDR4?

3) If TV use 14nm processors does that mean that TV's will use less energy watts?

4) Mobile screens are becoming clearer and more efficient like AMOLED HD, Quad AMOLED that I think is the latest and most efficient for mobile screens. For TVs are screens technology improving and becoming more efficient or we just get 1080 and now 4K?

5) Also how come TV don't say which version of HDMI they have? As 4K tv can really get the full advantage on HDMI 2.0 and HDMI 2.0a

6) Does newer processor improve on clearer TV and a better tv experience?

Reason I asking a few question for efficiency is because now a days efficiency is important on mobile and I guess people in general are more energy conscious.

Thanks
