I can't really comment or test further as my C8 has been collected now. I was previously watching Daredevil Season 3 which is in DV, I thought this looked excellent, and blacks appeared black.I was commenting on ASBL, not the content itself. But certainly on my C8, blacks were raised and washed out, but I'm seeing that on all kinds of Netflix DV content. Not sure if it's the content or the TV. It all seems washed out, lIke Waynej says, looks like watching it on a cheapo LCD
I didn't actually spot any content on Netflix labeled as HDR10, and given Hill House looks so much better with DV disabled, and some DV content looks correct in DV, then I just put this down to a Netflix issue.
