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.
Seeing as the new masters are now on Vudu, Amazon, GooglePlay, etc in various parts of the world, a DRM’d 1080p SDR version should come soon… hopefully. These masters need to be seen.
