The display assemblies are all different!
2015 is different from the 2016 and the 2017 is different again!
* 2015 - Original design with butterfly keyboard
* 2016 - Butterfly keyboard with TrueTone added
* 2017 - Butterfly keyboard changed out to ‘Magic’ scissor keyboard which altered the lid for the added height with TrueTone
