Just for clarification, my question was based on the fact that, at least for my ILI9844W display, there is an issue with GUI CALIBRATE (endless error loop). This makes it real hard to calibrate the touch part of the display after e.g. loading a new firmware or a OPTION RESET. So the fact that GUI CALIBRATE takes parameters which are not documented but seem to be the same as you can see in the OPTION LIST command, makes reestablishing the calibration easy once you successfully made it. You just note the values and can enter them manually if needed.
And yes, i wanted to make sure for me, this is a reasonable way to do that.
