This will be on your record if you are arrested and booked (fingerprinted etc). Does not appear that occurred in this case. If the store does not request prosecution, as it seems like here, the police often do not forward any reports for prosecution. Sounds like you most likely got lucky and should personally count this as your break in the system if nothing comes of it.
No, you were not arrested or booked so there would be no record. The likely reason is that you never attempted to leave the store so they did not have the necessary elements to constitute theft.
You weren't arrested which makes it hard to tell. It's been over a year which means the statute has run to charge you criminally (that doesn't mean they won't try!) Sephora is very strict about loss prevention, they don't normally allow civil compromises and the amount you took was high.. not hard to do as Sephora is expensive. Talk to a lawyer in your area.
