Hey guys I just wanted to chime in that rtings.com has confirmed the Black crush I am experiencing in dolbyvision content is present on there review unit as well. Just FYI. So this is indeed a bug in the tv.
Michael, do you think this DV black crush could be related to the experience I'm having (and others are having) in Dolby Vision, as described here?
In a nutshell, ONLY in DV, but on both external devices and the native TV apps, dark areas blotch out blue/purple. Noticed it in Stranger Things season 3 also, but still the best example is four minutes into the Netflix show Chambers, pics attached in this post. Are you seeing this effect as well?
