Permanent pier - doesn't matter. It might take you a bit longer to get it aligned but once aligned, the base can be at 45 degrees to level, the mount, goto system won't know the difference.
Portable - when the base is not level, a movement in ALT, changes AZ and a movement in AZ changes ALT. When you get close to the pole, and providing the base is not way out of level (eg 45 degrees) these changes become very small.
Can't interpret the angles from the bubble pics, different levels show different bubble displacements at the same angles.
In short it doesn't matter for either and levelling doesn't have to be perfect for an EQ mount.
