Subject says it all! 3/17 S90D
If you have the Tesla Remote (formerly Remote S) app, you can check the car’s configuration data. Based on the thread https://forums.tesla.com/forum/forums/how-do-you-know-if-vehicle-has-jul..., an uncorked car will have perf_config set to P1.
If I remember correctly uncorking only applies to 75D vehicles. Of course I could be remembering incorrectly.
Looking at some more old threads about this, I believe RedJ is correct -- only certain 75D vehicles could be uncorked.
And 75s. This required the new drive unit that was introduced sometime early second half of 2017.
There are very few 75s that have it as that configuration was discontinued a few months later.

My early January 2017 75X was decorked later that year. Performance gain was immediately noticable. Car had more power at all speeds. Off the line it became much quicker as well.
Needed to take it into service center. Did it while I waited.
If you want to know for sure if your car has been uncorked, a call to your friendly neighborhood service center, with the VIN should give you a reliable answer.
What does uncorked and recorked mean?
Uncorking provided a performance boost to certain Tesla 75D models. Recorking isn’t a thing. Maybe you meant decorking from Uncle Paul’s first comment, which is the same as uncorking.
