Streaming already or leaked?

A leak.

It's not been officially announced for PVOD streaming yet but the current and almost definitely accurate guess is 16th April. In line with Warner Bros'. 45 day theatrical exclusive run for their big releases.

The copies seem poor quality though. The best copy of the lot is a 6.6GB 1080P x264 for a near 3 hour movie? Shoddy bitrates. Also all copies seem to be stereo (2.0) which isn't the correct amount of audio channels, it's being presented in 7.1 surround sound in theatres.

11 more days and there will be proper 4K HDR x265 WEB-DL's in the region of 25-35GB with the proper audio channels.

High-quality pirated copies of 'Dune: Part Two' have leaked on pirate sites over the past few hours, beating the movie's official digital debut. The release is labeled 'WEB-DL' which indicates that the file was downloaded from an online source, but which one is currently unknown. Early copies include a tribute to the busted release group EVO, which leaked the first Dune film back in 2021.

The early leak comes with another noteworthy angle, the inclusion of “InMemoryOfEVO” in its filename. This refers to the release group EVO which was busted in 2021 by the Portuguese police, partly acting on intelligence gathered by the Alliance for Creativity and Entertainment.

That this ‘tribute’ to EVO comes as part of the Dune leak likely isn’t a coincidence either. EVO was the group that leaked a copy of Dune: Part One before its official release. Not long after, the group disappeared off the radar.

The EVO bust was a pivotal moment for piracy release groups. It marked the end of more than two decades of steady “screener” leaks, in which EVO played a central role in more recent years. The recent Dune leak is no screener, of course, but it’s certainly a high-profile release that will be watched closely by pirates, and Hollywood.

Supposed to be widely streaming Tuesday but pirates already have Amazon's.

It is available on IPTV services and it is a high quality, normally indicates a leak. This needs to be seen on the biggest screen you can find though.
