Setting Up Hyperbian – Ambient Lighting with your Screen

Can I ask what HDMI Splitter would get this job done the best with a PS5?
From what I can see with HDMI splitters, there will be a compromise - I’ll lose the 60Hz refresh rate, or I’ll lose 4K resolution.
Which splitter would allow the 4K 60Hz to go to the tv (with HDR), and still send what is needed to the Raspberry Pi without slowing things down?
