I have noticed range values of MimeType.TIFF_d16 are quite diferent than the original images.
Almost all values of a satellite image usually are between 0 and 5000 (e.g. this happen when downloading the whole image from Copernicus).
But, downloading raw images with sentinel-hub return images between 0 and 15000 or even higher.
Why does it happen? Does Sentinel-hub make any transformation before uploading the image? How that transformation works?
