Yes, it is a similar principle. Of course you will never be able to obtain the true HD source material. It will drastically improve the quality of the GOUT though with a frame detail somewhere between standard definition and true HD. In my view this is the closest you can get to a HD original trilogy, outside of the massive achievement of Harmy's despecialized edition. I do believe it is an interesting experiment in itself to see what the maximum quality is in terms of detail that can be squeezed from those three imperfect bonus DVDs.
