Quick reminder of the main source and its problems.
The 2011 Blu-ray is bad, really bad. Adywan’s grade with all its luster couldn’t correct a lot of the Blu-ray’s big problems, including but not limited to: DNR, Large Grain to disguise the DNR, Smearing or other artifacts on the first frame of some shots, and of course, Blown out highlights and crushed black levels.
The 2019 Blu-ray has been used to correct these problems, but the detail amount on the Blu-ray overpasses anything the 2011 has to offer (For ANH at least):
while I’m currently following the “2011 as a source with 2019 bits and pieces throughout,” this might very well change for a later version “V.3?”. So just keep that in mind.
