I've never owned a lex so I don't know for sure about external differences but I think if there are any, they are minor. Someone else could chime in for that.
If you feel like it, you can pull yours out and and see what it is. Both the Lex and stock AFM are shown in that pic...

Ok, but it would be nearly impossible for maitai69691 to know what he has just by that.
I think you should pull it and take a closer look and compare it to the pics above to be 100% sure, dude.
Just look on the inside. You don't even need another one to compare it too. The air bypass (on the bottom) is a different shape.
i believe the only difference besides size is the different shape of the air bypass as stated before. the are generally marked and unless you have a stocker and a lex, youll have to cross refernce the part numbers.
Yes. The stock ECU has its airflow map based on a set AFM size. If you change the AFM size the ECU has no way of knowing. Larger AFM, basically changes the A/F ratio as you're getting more air for the same fuel, as a side effect your FCO is raised. The change in A/F ratio is the reason you need to run 550cc injectors with the Lexus, or modify your A/F ratios through other means such as piggyback A/F computer, AFPR, etc.
