This sucks and im pretty dissapointed in it. I know i drive in NYC and apparently it is an ethanol blend city, so perhaps that is why.

Should i expect to see improvement since the car is not broken in yet?

Sorry to hear about your gas milage, it should improve over time as the car breaks in, also I think since you are in NYC, the biggest city in the U.S. might have an effect on it, obviously any city driving is going to yield lower milage. I heard ethanol lowers milage but from what I read the Yaris doesn't take enough to effect it meaning 15%n ethanol or so shouldn't effect milage too much if at all. Hope it goes up, keep us posted!

fearturtle44-you are correct, outside temp does effect how fast the engine will warm up (and when the light will go off), of course if you race it cold that will speed it up during the colder months (where ever that applies) but obviously you shouldn't and I don't advise "racing" a cold engine if possible. But from what I observed it warms up faster in the summer than winter which is a major give-in-what I also observed even if your driving on a 70 degree or so day, and you take a short trip, and the blue light goes off and you park for 30 min or so and get back in the car and leave the light will come back on as you haven't driven far enough to fully warm it up, but will go off right away or sooner than you first drove cause the engine has already been up to an operating temp for the light to go off and time of day effects it too. The light goes off when the engine reaches a certain operating temp which is not an optimized operating temp (as explained above in the example)-yes it gets to there but I'm saying when it goes off doesn't mean its at its full opperating temp yet...if that makes sense.
Enough of my babble.
