MCU 2 Vs eMMC issue?


I have a 2017 Model X. Last year in December, I upgraded the MCU1 to MCU2 without having any issue in MCU1. I paid $2500 for the upgrade and mainly did it to get things like Netflix and YouTube in car.

Now I see that earlier this year, Tesla officially recalled all pre-March 2018 cars with issue related to eMMC failure. Since I got my MCU2 upgrade before this recall and without having the back screen issue caused by eMMC failure, I wonder if that faulty component is still in my car or not? Or did they replace eMMC as well when doing MCU2 upgrade last year? Is it possible that they replaced the MCU2 but kept the old eMMC in my car as it was working fine when they did this upgrade last year? Can anyone here shed more light on this please?
