If it isn't pointing straight forward, then it will affect how you fly,a no it'll be frustrating - I had a similar offset with a Phantom 4 and had to have it replaced as DOA.
But,before you get to that there are a couple of things for you to check....
- first, nice n easy, dismount the camera, power cycle the inspire, then reconnect the camera.
- try a gimbal calibration.
- If that doesn't work, then calibrate your compass, then calibrate the gimbal.
- if it's still wonky after those, then try an IMU calibration, followed by a compass calibration, followed by a gimbal calibration.
- if it's still wonky, then try and find someone else with either an x4s or x5s to try and see if theirs works ok on your
I2, and if your x4s works correctly on their
I2.
Finally...
- start talking to the people you bought it from to get it checked out and replaced.
