The 'bump' is only fitted on 330's actually built as freighters & it is as you say because the passenger aircraft has a nose down attitude on ground.
Converted 330 freighters do not get the 'bump' as it is required on factory built freighters because the nose gear attachment points are different to get the floor level on the ground for ease of moving freight.
The converted freighters apparently have an electric system installed as part of the conversion because of the issue you say i.e nose down attitude on ground.
