Samsung had an operating system for STB and TVs before Tizen called Orsay. 2012-2014 (and some 2015) models have this operating system. Samsung is not using the "Orsay" name directly right now, they are calling it "Samsung Smart TV Legacy Platform". The identifier for these devices is "Maple" (in some cases "SmartHub;") and the device detector just returns as Tizen. Additionally, the model year info can not be parsed well.
