Ambilight Hardware Setup

Looking to finally dive into ambient lights for my TV, but still unsure if I have 'ideal' tools to achieve a good setup.

Here's what I drafted so far:

• SK6812 RGBW Led Strip Light WS2812B (5m, 60 LED, IP30)
• 4K 60FPS Capture Card with Loop
• Raspberry Pi 2/3/Pico or ESP32?
• 12v Power Supply
• Hyperion/WLED

My TV Setup:

• Sony 55" 4K TV
• Denon AVR

I'm not looking to spend much hence the choice of equipment, but just wondering if I have the right per LED ratio for the light strip, and if the Capture card will do the job.

Thanks

I'm a little bit confused, which one of those supports 4K 60fps HDR output connected to an AVR using a RPI3?

I really need a splitter just a grabber as it's connected to an AVR.

Thanks
