Does PIFUHD 3D reconstruction model preserve sizes?

This is little conceptual question. I am working on 3D reconstruction using deep learning from 2D images. I came across PIFUHD model which is developed by Facebook and I have a question regarding that does this model preserve sizes of humans like arm length head diameter or any other body part? If it does can you please cite any source where you came across. Or do you know any other pre-trained model which does that? I would prefer deep learning based approaches but even if you have any other ways please mention here any help is appreciated.

For more detailed idea about what I am trying to say: Suppose there is a person in 2D image is 5 feet 11 inches does 3D reconstructed image will give me 5 feet 11 inches tall person or there is fixed height person is returned back or there is no fixed such things?

Any help is appreciated.
