FWD windows already tinted?

I am picking up my Model X 90D on 8/1 but I drove behind the local Service Center today to get a preview! It is an inventory X (963 miles). I immediately noticed that the windows on the FWD's have a dark tint, obviously darker than the front windows. I am not sure about the lift gate window. This was a surprise to me. Anyone else get an X with tinted windows?

It is not actually tinted, just a dye in the glass. They all come that way, as do pretty much every SUV we have purchased. I added tint to the front windows, plus clear tint to all the other glass on ours.

Even my Leaf has tinted (or pre-darkened, as @rsampsonjr says) rear windows!

What blocking effect does it have on UV?
