After further testing out DV on my c8 with test patterns I noticed that DV on my tv crushes black. Anything under 1% is crushed, regardless of how I tweaked it. I tried raising the brightness or messing with the cuts in the SM with nothing improving the black crush. On HDR10 I can see some of the lowest levels, which for an oled is pretty amazing. I turned off my DV on my Panasonic ub820 and will be sticking to plain HDR10 from now on, in which I get 780 nits and excellent eotf tracking. My panel uniform is near perfect, I am in no rush to upgrade my tv. LG really screwed up the DV on the c8 it's so sad.
