Here's a look at the impact of different denoise values when using hires fix. At 0.1-0.2 the fishnets are odd and the nipples don't show well. 0.3-0.4 look pretty good while preserving the original image. At 0.5 we start to deviate from the original, but it's not particularly coherent. 0.6-0.8 start giving us new attire with increasing detail/complexity the higher the denoise level.
