Yeah, unfortunately, at the same time this resulted in even more white clipping (look at the reflection in R2's dome). But it's just a little and I feel that comparatively it is a small price to pay for all the detail recovered in the dark areas.

I'm glad you also think it was a small price. And actually it's not that much clipping, what I did was to push the highs closer to white to make the movie look closer to the original. The shades of white being closer to white sometimes creates an illusion of them being clipped. The raw blu-ray is badly underexposed so I thought it was necessary.

Actually, when examining that brightest part of those screenshots in photoshop, the only color which peaks at 255 is blue, so if something was clipped it was some blues in the middle of the brightest part. The rest was just pushed up towards white and that's why it looks clipped when it's not.
