Ok then - lets see if I can get Son of SJ on board - bearing in mind I am a jedi and he is but a mere padawan
There is one main negative with watching a TV compared to a PJ - thats the frame / bezel and the wall behind it.
People use bias lights to help the eye focus on the screen - I used to do this my my Kuro but found it more of a distraction with the 65VT65 so chopped it
After seeing the PJ in a completely blacked out room (by blacked out I mean no ambient light or relfected light from the screen, not just black out curtains there is a big difference) I noticed just how much the rear wall was visible and how much the VT65 frame was visible also. If it frames the TV and you can see the frame you can see your watching a TV. This was one of the things worse about my setup compared to the PJ setup that I fell in love with. Literally love at first sight it is real *acute*
So to stop this you can put up black velour on the wall behind the TV - you can buy 5metre rolls that have adhesive backs, its easy to put up because you dont have to be perfect like wall paper, just keep it the same way up because you cant really see imperfections once its up. It actually looks a lot nicer than it sounds as well I think - its like a plain feature wall.
You then have the tv image coming off a lightless background - this will have the effect of increased contrast, it gives the image more pop because your eye is not seeing the rear wall at the same time as the tv, its seeing just the TV and whats in front of it.
The next trick is depending on the TV framwork and bezel - probably no need on a ultra thin OLED but the silver trim of the 65VT frames the whole image.
You can cut thin ish slivers of the black velour and use it to cover the frame only - def not the screen or the speakers, all the way round. Its only a very light adhesive so it comes off easily and wont leave any marks or anything so as long as your careful there is no chance of damage or anything because its only being stuck to a hard plastic frame - However I should add a disclaimer to this - I hold no responsibility etc if someone tries it
For your efforts what you get now is an invisible TV - you cant see your watching a TV anymore - your just watching content and it works a treat if you ask me - assuming you are watching the TV in a light controlled way.
Just an idea
