To be clear the amazing bit it not the picture or the sound, they are the same excellent quality of an LG OLED 65" 4K TV and sound bar. The wow factor is the form factor. This is a "wallpaper" TV.
What is a wallpaper TV?

How much?
It costs more! The price comparison today was 77" LG signature OLED £8k, but wallpaper version £12k. I went for the 65" wallpaper version. My wall has space for 77" and in some ways I am thinking I should have done that, but to be honest, even I am not made of money. As it is, those prices meant upping the mortgage!
Is it really that thin?
Well, yes! Even fitted to the wall with the supplied wall bracket, it is that thin. It claims 6mm... It is. I held 5 credit cards against the wall to see...
Is it a good TV?
The panel is the same as the non wallpaper, but designed to be a thin panel on a wall. Apart from the fun of installing it, it is the same, and is awesome just as before. UHD and HDR, and the awesome contrast with true blacks you get with an OLED TV. Stunning.
Black is black!
Is the sound good?
Seems so - it has a "sound bar", and they have gone all out on the gimmicks with the tweeters motorised coming out of the sound bar when you power up. I even make a video especially for that feature... But actually, yes, very good sound - it even has a calibration mode using the microphone in the remote to adjust for the room acoustics.
How hard is it to install?
Well, I was impressed, it was not too hard, and basically James and I did it! I was scared we would screw up, but no, we managed. I have a nice installation video... All I needed was some wall fixings, and actually some were even supplied (we used Fischer fixing plasterboard fixings).
The flat cable!
The flat cable was an issue, it is a certain length and no "plug" at the panel end just hard wired in, and a tad inflexible. As you see in the video it was too long and meant the sound bar at the front of the table. But it does come with an extender which we used, and looped back in the base/cabinet, and made it work nicely. It is one thing to consider when choosing the height of the TV.
This meant I could have the sound bar further back.
Long term it may be sane to hide the cable within the wall, which would be pretty easy, and have a small floating shelf for the sound bar. So many ways this could look "tidy" with a small amount of work.
