I have the same car, same oil, same problem. Service people at the dealer 
didn't consider it a problem. An independent mechanic, trained by Ferrari and 
very knowledgeable about these things (IMO) told me that's typical for 
engines with forged pistons. Apparently, they need to warm-up a bit to hit 
their optimum tolerances. It's not a problem unless you like to use wide open 
throttle first thing in the morning. I give it a minute or so and am light on 
the throttle until I see the temp needle at its normal position. Ferrari 
recommends an even more cautious warm-up period as a way to minimize engine 
and drivetrain problems.
Hope this helps
