I thought there was, though, previous discussion of Tesla using non-automotive grade electronics in places. Using stuff that's rated for the heat, moisture, vibration, etc, implies lag time as opposed to "latest/greatest".
The big screen is the common example of this, as they couldn't source an automative-grade screen that big. It's suffered several issues due to heat and UV exposure.
The screen is automotive grade. The yellow discoloration has been traced back to a supplier changing the adhesive chemistry on the LCD panel to save cost.
Seems like they made a calculated tradeoff here to sacrifice some reliability in further-toward-the-fringe conditions (extremes of heat & humidity) in order to get some wow factor with the screen.
They also made a calculated decision not to recall the device nor properly replace the screens for those affected. Forums are littered with stories of people who suffer from the yellowing and are forced to live with it.
The yellowing is a purely cosmetic issue. The more serious earlier problems were fixed under warranty.
Lots of people have had success getting the yellowing fixed without charge after going through arbitration. I'd prefer if they would fix it under warranty, obviously, but it's not a huge deal.
