Blu-Rays

I still own and watch the standard DVDs of the OT basically because I refuse to spend more money on the Blu-Ray copies. That being said, I was curious for anyone who owns the Blu-Rays, my question is are those noticeable gray boxes that surrounds the tie fighters like towards the end of A New Hope and etc. still appear on the Blu-Ray copies or was that corrected for the Blu-Ray release?
