How closely have you looked at yours? Mine was NOT fully fixed via this method, I have a thread over in the S section if anyone wants to see more details about their arbitration process (Yellow screen? Force Tesla to Replace it!)
Here is an after photo showing the yellowing is still there(note: this is after the second attempt, I forgot to grab photos after the first attempt):

Mine no longer looks like that either. My screen was baked on 07/15 at the Burbank Service Center and its completely free of any yellowing or haze.
