the white sheet, the strands or texture looks larger in the sigma

No it is from Aliasing. Lack of an AA filter. It is the same phenomena that produces 5 lines from 9 on the res chart in the review. As the details get smaller the actual ouput gets bigger. This gives the impression that it is show more detail when in fact it is obscuring the real detail and giving a bigger false pattern.
