Are we looking at the same thing? I took a screenshot of one of the videos in question and compared it to the blu-ray:

It only required a small color adjustment to closely approximate the Blu-ray, and the cropping/warping is identical. The Blu-ray also has more detail, probably because it isn’t compressed for the internet.
It’s the Blu-ray with a small paint job.
