not sure what i can ever contribute here but might as well post about this since i don't think everything is too well known and they're kind of cool!
what DCPs are is just ProRes/DNxHD (distribution format: bluray, streaming, HDTV, cinema, etc.) files but rewrapped losslessly to a jpeg2000 image sequence at 24/25fps in xyz12le 4:4:4 colour. (uncompressed chroma and a high colour bit depth at 12. might be upconverted from 8/10, or 4:2:0/4:2:2) [still not as good as 16bit, 20bit or 24bit native] with a lack of letterboxing usually followed with unique sound mixes for theaters. they're nearly always encrypted but quite a few have leaked
what makes ProRes files so neat is the fact they're 'visually transparent' encodes and are only encoded in I-frames meaning no previous (P) or previous/next (B) frames are used as reference, resulting in amazing video and perfect grain (P and B frames have a chance to mess that up)
my neighbor totoro 2x DCP
two of the gkids DCPs were leaked publicly, apparently because someone was ment to upload trailer DCPs (usually unencrypted afaik) but messed up...
a unique video transfer and a major improvement over any home video version! the two DCPs also differ slightly.
apocalypse now DCPremux (redux master [2K] - theatrical cut)
it's public but the remux that's out there is messed up. it's encoded as 48fps with duplicate frames which i assume ruined the entire file as it freezes/stutters during scene transitions, probably since the codec can't handle those bitrate spikes any more. (jpeg2000 has a limit of 250mb/s)
i assume whenever they were toying with it they also messed up the colour space as that's problematic too...
barely any difference from the bluray
escape from new york DCPremux
on private trackers
tombstone DCPremux
originally on HDbits - removed as they don't want to be a source for DCPs
back to the future DCPrip BDremux
this one's public and well known... slight improvement over the bluray from the same master. sadly uses bluray audio
the hateful eight 2160p RU "DCPrip" (WEB-DL/WEBrip/VOD/VODrip) FAKE!
it's public but as stated by the teamHD people, they obtained it thanks to their WEB-DL fund so it's not legit. the russian bluray is also 25fps like this "DCPrip"
this is just a different source (slightly different colour grading - no tint) from the typical bluray/WEB-DL sources presented in UHD.
it might have only been intended for cinemas but that doesn't make it a DCPrip. the same source is also on the swiss and - italian (apparently?) blurays in 1080p
apocalypse now ProRes 4444 2160p (final cut)
public, leaked from a streaming insecurity
barely any difference from the bluray
avengers: endgame ProRes 4444 XQ (IMAX)
unsure if it's leaked yet but source is ~3TB and comes from HDbits. since there's no UHD BD release it's slightly better than the WEB-DL, PQ could be better
the needle (1988) ProRes 422HQ
it's public, massive improvement over the blurry and denoised french bluray. also apparently screened as a DCP!
