My dealership replaced the air in my tires with nitrogen. Nitrogen exhibits less pressure change with temperature swings and also nitrogen is less likely to migrate through tire rubber than is oxygen, also helping to keep a more consistent pressure.

Regular air is already 78% nitrogen. The difference you'll see in loss of pressure and pressure changes due to temperature is minimal. While 90+% nitrogen is common in race cars, it one because 1-2 psi change can alter the handling of the car and they also deal with much higher tire temps and meed consistent tire temps during a race. But on the street, no one will notice the difference between 36 or 38 psi

If you're talking ambient temperatures, you're not correct.
Consider a day where its 80F during the day, and 40F over night, which is quite common here in PA. If you are at 35psi, tires are "cold" and at ambient temperature of 80F, and you go back to the same tires in the morning, assuming ideal gas law, and no leakage through the seal, the tires could be as low as 31psi at 40F. This can potentially trigger a light depending on the set point in your car. This of course is based on the air inside a 225/60/18. This will change with a different size tire, like same math with the rear tires of my Camaro, which are a 295/30/20, I can potentially lose 5psi, or a Z06 Vette with 335/25/20, it can almost reach 6. That's a huge amount.
Consider, in our old super gas and super comp drag cars that ran 16"+ slicks, the tires could change 1/2 psi just because the sun hit them for more than 3-4 minutes.

A few things I miss about my '13 ES 350 that I don't have in the NX F Sport:
No coin holder.
No dedicated sunglass holder.
No cooled seats available on F Sport.
No door courtesy lights.
No real leather available on F Sport.
No third cupholder in the center console.
