Correct me if I’m wrong, but didn’t there used to be a UPS and FedEx 757 livery? I can’t find them anymore.
These liveries were removed when the B757-200 received the rework as it was the passenger variant of the aircraft that received the rework and the developers decided that it wouldn’t make sense to keep these liveries on a passenger variant of the 757 and not a freighter variant.
Hope this helps provide some clarity mate! 😊
