Yeah, but if you really want to get more nitrogen in, you need to use winter air.
Air… as I said above is 78% nitrogen. When they fill your tires with straight nitrogen you end up with about 80-85% nitrogen inside the tire. So basically just use normal air because you're not getting any benefits as minimal as they may be anyway

Ideal gas law, as Temperature changes so does tire pressure. As a general rule, a 10 degree drop in temperature results in a 1 lb drop in pressure. (And yes, it happened on your Caddy, too.)
Made a tyrepressure/temperature calculator for dry gascompound in tyre (fi Nitrogen filling) and Wet (normal air), in that last I am first, I think.
In this RV map
So play with it, also part 5, and see that the influence of water in tire is often exagerated by the Nitrogen-lobby.
So if you go from dry calculation, you are not doing bad. Made a list for that, in wich you search back your cold filled pressure at 70 degrF, ( but if you go from 60 degr F, it wont give dramatic differences), and gives howmany degrF the temp changes per 1 psi.
Then you can even calculate by head when driving, acurate enaugh the temperature in tyre, by the pressure change tmps gives.
Then some tmps calculate back to a reference temperature in the receving unit, mostly 68 degr F., before giving it on the display.
I thougt Tesla too, but could depend on the setting.
Then your question.
To my conclusions (opinion), you can let the cold pressure flow with ambiënt temperature, for safety of tires, so never blead down the higher cold measured pressure on a hot day of 100 degr F. cooling down if tire material is worse then, because of the smaller temperature differences between tire-material and in and outside tire air, but the lesser deflection the higher tirepressure gives, gives lesser heatproduction, wich compensates the lesser cooling down.
So never blead down, not warm, not cold pressure.
At low ambiënt temperature the other way around, but then pressure is allowed to highen up for energy saving and roadhandling.
Here the list, you only have to remember your filled cold pressure.
Also have a list for bar and degr C.
