Mandalorian is “out there” in 4K HDR, so the drm has clearly been broken on day one, so I think for those of us who won’t get D+ until 2021 (and believe me, if I could get it now, I’d be the first in line), someone will put the new masters out as well.
Apparently the only way to snag the files is through Nvidia Shield, and each time you do it, they ban that specific hardware so you have to use a brand new Shield each time. There’s also the fact that the “release group” doesn’t share their DRM crack. So I wouldn’t expect any more WEB-DL releases to come out of Disney+ for a while, it’ll probably just be WEBRIP recordings from an HDMI splitter, and even if that isn’t the case, a pirate group like that isn’t likely to spend $200 per film or episode to rip something that “already exists” in some form over entirely new content like The Mandalorian.
