Having found the answer why the blu ray still have the same odd colors and wrong lightsabers:

"A lot of things that look a little different on HD or DVD are really the nature of how video treats color space."

It's as simple as this. There is no workaround for this. -sarcastic- again

Some quotes from the now famous restoration article on sw.com:

With the ... release on ... Blu-ray disc ..., a release that required meticulous optimization of picture and sound.

I don't buy this. This doesn't look like meticulous optimization of picture.

However, that is not to say that that work done for the 2004 release was simply ported over to Blu-ray.

No simple port? I don't buy this! What exactly was done to the video? I am not talking about content changes as a restoration articles should neither.

"It went through three phases of QC (quality control) processes," describes Diane Caliva, Production Manager for Media Operations at ILM.

After seeing the CHD video samples and snapshots I can only laugh on the 3 phases of quality control.

There are a handful of such technical shot corrections in addition to the cleanups throughout the films.

I buy it that you only made a handful (that is basically not more than 5) of technical shot corrections througout the films. With cleanup they probably only mean dirt removal and corrections of blemishes and warping on the image.
