I was confused about this as well (especially since the C1 didn't natively support Amazon for a long time due to licencing issues between google and all, but the app now does)
Basically 2 things have to be there
1st) it has to be labeled as a UHD 4K video.
2nd) when you select the video in the details section you should see a [HDR] tag on it next to the 5.1 audio tag and the like.
I wasn't able to get some content to work right since Amazon does a bad job of sorting content (hell I cant find 4K Grand Tour episodes anymore, let alone the HDR stuff... just 1080p)
But when i loaded up a more recent Amazon Prime originals which had the UHD banner on the thumbnail, and [HDR] tag in the description. As soon as the video loaded I had an HDR10 video signal as it buffered from 480p -> 2160p.
So try that, find a known good HDR/4K video on amazon. See what it does.
(also you can try the Builtin YouTube app and play proper HDR10/4K videos. It only plays as 1080p when I directly cast from my phone, but using the internal app through the VIA selection screen i can get 4k60 + HDR just fine such as a DigitalFoundry episode.
