I think there are some issues, at least with screenshots provided in post 639 . I made sure to save them and verified them by size. I didn't look at the "RAW" versions, just the others

The biggest easy one to see is the bottom of the blue dress . Look at the texture loss at the bottom in both magicyuv and cineform compared to the source. The noise and grain pattern is smoothed over .

There are some color sampling issues too . Look at the small yellow flower spots. Some of the smaller ones almost disappear in some spots in the cineform screenshot . The source has more "orange" spots, but they become yellow and more desaturated . Even the magicyuv screenshot is affected (albeit less)

I think there is an issue with that capture setup , and or method of taking screenshots

EDIT: or did I misunderstand ? Those were re-encoded x265 screenshots ? So those were caused by x265 ? That would make more sense
