No I couldn't tell you; been maybe 5 or more. One indication that a release is bad is that reputable remuxing groups have not released a remux of the torrent using that source. By reputable remux groups just to name a few like FraMeSToR, Epsilon, and KRaLiMaRKo

By the way, some UHD remuxes come pretty close to the official release, but some take much more time. They haven't fully cracked the tech behind UHD yet?

There are some talented people transferring hdr 4k movies that are just as good if not better than studio releases. And believe it or not, the sources don't come from uhd disks!
