Hyper elastic analysis - True (Log or Hencky) strain results?

Hi all,
I am running a nonlinear (large strain) compression analysis on a Hyperelastic poly urethane material using Mooney Rivlin constants and modelled using Plane 182 Axisymmetric.
Can anyone verify whether the POST1 stress and strain results will be in True scales. The theory manual (sections 4.6.7 and eqn 3.6 )says it will be in true scale but in section 3.1.6 it says Hyperelastic elements output in other strain measures. DO they mean Hyperelastic elements as from HYPER 58, 58 etc.?
Does this apply to LS Dyna output results too?
I would greatly appreciate if anyone could confirm this.
Thanks and Regards
JJ.
