Yeah, the front windows had a layer of film tint on them when I bought it. It is definitely different than the way the OEM tint in the rear windows is done.
I bought mine used from a Lexus dealer - it was a returned lease through that same dealer. So, I’m not sure when the film was put on prior to my purchase, but the other new LXs that show up on the lot look to have the same level of tint applied to their front windows. (When it’s being applied, I have no clue. )
