Most likely, it was overfilled.
The fluid level needs to be adjusted between 95F-113F with 104F being the ideal temp.
Was the vehicle allowed to cool for at least several hours before the fluid change and level adjustment was performed? If not, they most likely "ballparked" the fluid level (which a lot of techs do if the car is a waiter) and the fluid level will not be correct.

If some fluid was spilled, I would imagine they would clean it... And it is pretty hard to spill because the fill pipe makes it easy to fill.
Also, look at your receipt. I think that transmission takes approx. 4.1 quarts on a spill and fill.
The 2013 might still have a dip stick, which makes it easy to check. Not sure...
Finally, I would service that CVT 2 times as you only get a portion of the fluid out.
Good luck.
The amount used for a drain and refill really varies. It depends on whether the vehicle was drained while level, at an angle, etc. I have seen some significant variations on Nissan automatics. It is best to pump in 3 quarts when the trans is cold and see if fluid starts to trickle out of the overfill tube. The trick is to pump in enough fluid so that when you are below 95F there is already a small stream coming out of the overflow plug. You want the trans to be slightly overfilled below 95F, but not too much. Once the temp rises to 104F (the fluid level will continue to rise), you can remove the check plug one final time and allow any excess fluid to drain out. Note: If the trans gets overfilled too much, the amount of time needed to drain the excess (once you reach 104F) will be too long and you will be outside of the allowable temp range.
