I do know this does work on some screens I've used it mainly with built-in displays on PyPortals. I'm not sure about whether any screens reverse the values like you mentioned.
It is fairly typical to need to change the calibration values though, the defaults tend to work okay for me as long as I don't need precise accuracy with the touch point. But if I get them dialed in the accuracy goes way up and it can register touches on relatively small screen regions successfully.
There is a script in the examples folder that can help find calibration values for your particular screen: https://github.com/adafruit/Adafruit_CircuitPython_Touchscreen/blob/main/examples/touchscreen_calibrator_built_in.py
from adafruit_circuitpython_touchscreen.
I've made #23 to support both the existing behavior, and the behavior that's required for ILI9341.
