Saudi Arabian Boeing 747SP At Boston Logan Airport - Interesting Window Treatments

This has become a frequent visitor to Boston lately. Note at 1:01 in the video that the cabin windows appear to have some sort of external rectangular enhancement. I have never seen this on a 747 before. Anyone know what those rectangles are?

Good catch!

Appears to be an extra piece of material around each window.

Curious!

3D windows...duh.
