EOS 5D Focus Screens

[gemseeker]

Hi All - just a newbee to Forums - just a bit confused with Canon nomenclature in its various publications regarding Focus Screens - my camera manual states the screen supplied with the 5D camera is a standard Ee-A which I had replaced with a Ee-S for better manual focusing.  Unfortunately the in store tech grabbed my standard screen with his fingers when he was removing it from my camera before I could say anything leaving finger prints on the screen at which I spat the dummy!!!

Short story is they have replaced it with a new Ee screen [and no other designation/name on the packaging or on the instruction sheet that came with it] and note it is not an Ee-A screen.   Are these two screens (Ee and Ee-A) both one and the same?  I tried canon locally but their literature is older than that which shipped with the camera and is even more confusing in this regard.

Can anyone please correctly advise me?
