Thanks! Here’s the link from amazon.
I have this one on ALL 5 Tv's and used it on all my previous ones too ! There isn't a hardware one, the peel & stick to the tv ones work best for either stand or wall mounted !
This one also lets you choose the color & change it as needed, along with the brightness of the lighting ! Plus it's NOT expensive, just make suree to get the correct one for your sixe of TV ! Cheers & Luck !
It's called bias lighting. Basic white strips are cheap, ones where you can change colours are a little more. This is a popular one https://www.amazon.ca/Luminoodle-Color-Bias-Lighting-Powered/dp/B076X85988
Its main purpose is to increase perceived contrast on LCD TVs (not needed for OLED) when watching in a dark room. Other than that some people just use it because it looks cool. Gives the room a little bit of light without putting glare on the screen.
I have that exact TV and here is the led backlight I used. Fits perfectly.

I'm not sure you should do anything to the wall. It would distract from the entertainment on the TV. What I think would look cool is adding bias lighting behind the screen, which you could match the colors of your furniture/rug/whatever.
If you want non-adaptive bias lighting (doesn't change with what's on the screen), I'd recommend Loominoodle.
For adaptive bias lighting, it's a little more complicated. If the television doesn't come with it natively, you have to run it through some sort of hardware to figure out what's going to show on screen and react to it. The only one I know worth trying is Lightpack.
I used an LED bias light! Something like this
hold the Down-directional, then use the right stick forward & back to adjust the FOV, I play all the way out to get the widest view. This helps a lot. Don't play in a dark room, Get some Gaming glasses , I have Gunnar glasses. Also if playing on a TV, sit back away so your whole vision isn't filled by the tv. I also have Lumi-noodle lights on the tv, the back-lighting helps with eye strain and other issues.
Hope this helps, Cheers !
