They have a mistake. I updated 3 of my applications between August 23rd and now, and for all of them, the 512x512 icon has a glossy effect, although I checked the "Prerendered Icon Flag: true" for all. I had no problems with the applications presented a week before.
I have not changed my Xcode or anything else, meanwhile, this is not related to the developer. I wrote Apple and I am waiting for an answer.
I also noticed that when I register a new application and download the 512x512 icon, it does not have a glossy effect, although icons downloaded without binary have always had this effect. Therefore, perhaps they have updated their code, and now they consider this variable to be false when it is true and true when it is false.
