Yes I definitely think that the 4k scans are happening, but there's a couple of things to worry about.

1. Is the 4k treatment only being applied to the SE? I know the video has the blue escape pod door, but I honestly could see them just forgetting to turn it black again. If that's the case would they still include the OUT but in lesser quality?

2. Is this a scan of the OUT, but they for some reason thought that redoing the lightsabers was OK? I for one don't think the sabers in the video look exactly like 04, but they definitely dont look like the originals.

There's also the possibility that they are giving the 4k treatment to both the OUT and the SEs.
