Cololight or Nanoleaf or Hue

I'm looking for a simple solution to install LED strips behind my TV without a DIY approach. From what I've seen, only Hue, Cololight, or Nanoleaf seem to fit the bill. I'm also wondering how many LEDs per meter I need – 30 or 60 for a 55-inch TV?

Do I need an additional light channel with a diffuser? The TV is mounted close to the wall.

Nanoleaf offers several products, each with its own pros and cons.

The Essential HD LED Strip (60 LEDs per meter) doesn't seem to have a 90-degree adapter. Are they flexible enough to bend easily?

The Nanoleaf PC Screen Mirror (30 LEDs per meter) only uses USB. Will it work with an LG TV?

The 4D Screen Mirror (30 LEDs per meter) has a camera. Can I use it with Hyperion even without the camera?

Cololight

LED strip (30 or 60 LEDs per meter) looks like there might be 90-degree adapters available for it, or you could use extensions.

Hue

Philips Hue Gradient LED strip (54 LEDs per meter), but for that I'd first need the bridge or another Zigbee server.

Or the newer OmniGlow Lightstrip.

Just a quick addition regarding Hue: there are quite a few products available. Some people say that the curtain strips only have 5 or 7 zones, but this only applies to the Hue App? Surely it can control more than that?

The following three Hue products would be suitable for me:

Philips Hue Ambiance Gradient Lightstrip (144 LEDs per meter)

Philips Hue OmniGlow Lightstrip (840 LEDs per meter). I'm wondering if such a large number of LEDs can be controlled.

Hue Flux Gradient Lightstrip, because it supposedly has 90-degree connectors, which would allow for the best installation.

Philips Hue Play Gradient Lightstrip (270? LEDs pro meter) but only for 3 sides and therefore not for me.
