Any idea why the Inspire X5 + 17mm 1.7 horisont is not straight in 4K25 mode? I mean it is not tilt left or right: it is like a wave.. like in x3 camera problem, in still pictures the horisont is ok. I just change the video mode to photo mode.
Gimbal calibration is tested. Nothing change:

I would try a cold IMU calibration on a level surface followed by a gimbal calibration.

Actually it's not too bad, IMHO. Every lens will show some barrel distortion, more or less. Particularly when horizon is at the top of the frame. Your sample video shows some barreling, but tilt to right is more obvious. This is easily correctable in Go app before filming, if gimbal calibration will not help. Barrel effect on stills can be corrected further (beside automatic lens profile correction) in decent editor like Photoshop.

You did not happen find out how to calibrate the Z3 did you ?  I have seen that question posed several times Now and would love to know if it is possible after the Initial calibration .  I wish DJI would write better manuals , I mean they Have No mention of it anywhere that I can find for Calibrating AFTER the initial start up .

A far as I can remember Donnie, when you first fire up the Z3, you get the option to calibrate by pointing the camera into the distance, after that, I have no idea.
