Perhaps stupid question, have you tried another tire gauge? 
You never know which is 'correct' without a standard...

This is what I used. Also used this. Both were different than the TPMS and from each other.

Still Trying to Figure This All Out
Mine seem to be all over the map (well two of them agree) until the car is driven for about 20 miles by about 2 lbs. Then they all seem to reach the same maximum.
It's part of my to do list to apply a highly accurate tire pressure gauge to validate against both cold and hot readings.

Those seem to be the same thing? I have no idea what the accuracy and repeatability of consumer tire gauges is. Accuracy may be a PSI or so. Repeatability may be more precise.
But we still don't know which of any of them is 'correct', which is the problem. I might trust the electronic ones (TPMS) more. I might be incorrect. I like @aesculus 's plan.
At least, do it once so you can trust things.

As the saying goes...
