Meta is correct on the height limit. It is 500m altitude. You will need to change this in your go app and accept the responsibilities.
DJI has used 120m as height as a common guidance for all countries. But DJI has also used 120m height as yard stick for distance to calculate and publish the specs under controlled conditions to make comparisons easier. Think of Pythagoras theorem (a2+b2=c2). The higher you go, the shorter the horizontal range. If they used 500m as the ceiling, and if my calcs are correct, the range will drop from 1.2km to 1.1km in the P34K.
Hypothetically speaking, if you increase the ceiling to 1km, the horizontal range would be 670m.
Now if they didn't use the standard, then it would be very hard to compare without doing some calculations.
