Hello Philipp
According to the manufacturer it has hdr (10 is the bit rate where pass through)

4K /UHD 4096x2160 at 60hz possible with hdr

4K has a resolution of 3840x2160.
And the cable can run up to max 4096x2160

So the cable can send up to 18 gbps


So I also watch hdr movies over the cable and it works unfortunately I can't tell you how high the bit rate is but think it works for sure

I have the link from the manufacturer for you
