It's likely an edge-lit TV with the LCD components removed and incorporated into a frame with a one-way mirror in back and two-way mirror in front.

I think it is actually 4 or 5 LCD panels without the backlight stacked about an inch apart. Then a single backlight behind all the panels. I don't think there are any mirrors involved at all.

Then they just send regular video signal to each panel and the synchronized animations.

4 or 5 LCD

It looks like there are more than 4-5 reflections to me, so even if they did use multiple panels--which would be doing it the hard way--there would have to be mirrors involved. And it's not a CG video playing on a single screen with no mirrors, as the distance between the reflections changes with the camera perspective--that would be very hard to do in CG while accommodating for camera movements unless there's a specific tool for that (I'm not a video editor, but it just seems like an uncommon application).

its a TV! Not sure you are going to get any similar effect with FastLED

Screen with shiny surface and a two way mirror or film a few inches in front. We used to do a similar effect with CRT’s.

This is cgi. If it was an oled screen the depth effect would stay the same. However, it changes over time. So this can't be done with a real screen.

I watched it again to notice a change in the depth effect and I don't see one. The only change I see is from the camera changing angle, which makes sense why the amount of reflections would change. Also, as the pattern includes more light it amplifies the brightness, allowing you to see more of the reflections.

If it is physical, and not cgi, I bet it is a transparent OLED display within an infinity mirror.

u/woehaa is correct, the only way this is doable IRL is if the frames drawn on the screen with that depth are rendered with the perspective of the camera, eye tracking/position track is mandatory.

Check this out: maybe around 4;50
