In general when playing back animations via spine-unity there should be no difference in playback speed.
Could you please check what your Dopesheet FPS
settings in Spine is set to:
Playback - Spine User Guide

Please do not adjust any playback speed on the Unity side, if it does not match automatically then something on the exported Skeleton asset is wrong. This is under the assumption that you are not calling SkeltonAnimation.Update()
yourself.

Spine exports every timepoint in seconds, on the Unity side it is played back based on frame delta time, which is also seconds. So I wonder what your developer meant by "not the same animation speed measurement", in general there is no difference.
