Yes it appears to be, but it will not tell you if it is out of QC Hold. I believe the vehicle will remain in "Freight" status until it reaches the dealer.
I'm looking at the spreadsheet and it appears 1300 vehicles in Freight or Ground status have been updated in the last 3 days.
Unfortunately, in every previous Toyota I have owned (6) I have always had to upgrade the speakers or other.
If/when my Limited arrives, I'll post back on my thoughts on the JBL system.
