Yes, it has gotten worse. The extra cartoon aliens, the Blu’s DNR, “pretty hot”, etc. If I’m not mistaken, the colours are as messed up as the OT, too.
As for Yoda, however different Yoda looked from the OT, the special effect was still well executed. He was there with Samuel and the others, and the mannerisms were top notch.
The colors of the blu-ray are very strange, with many parts of the film having a purple tint and others (especially the Tatooine scenes) being brown and desaturated, to the point that some gradients may be gone.
And yes, CPY was a decent effect, so I’m torn on how I feel about that.
