Apple 4K TV -> Denon AVR-X2600h -> Sony Bravia a8g

I had a new home theater system setup and am having trouble getting the apple 4K TV to output Dolby Vision or 4K HDR. It outputs 4K SDR without an issue but when trying to switch to HDR or Dolby Vision, it resets back to SDR. I have gone through the various settings within the Denon including switching the 4K Format to Enhanced. I checked with my installer and they used a 25ft HDR 18awg HDMI cable (Belkin) and I believe the length of the HDMI is the issue. Should switching to a 12ft version of this HDMI cable resolve the issue? If not, then can i plug my Apple 4K TV directly into the TV and pass the audio to the receiver? If so, how is that accomplished?

Thank you!

So after speaking with customer support with Denon and Apple, I believe the issue is definitely the length of my HDMI cable (it is 25ft). Will try using a Fiber HDMI and see if that allows HDR/Dolby Vision to work.
