For me the converted file looks exactly the same and is 16 kB larger (out of 11MB).
Which version of mutools did you use?
I tried 1.23.10+ds1-1build3 on linux and 1.23.0 on windows. They create slightly different versions with no visible difference.
I had to replace DeviceGray with mupdf.ColorSpace.DeviceGray for both.
Maybe my pdf is different, I downloaded it a long time ago, and can't find the original anymore. I'll see if I can find a publicly available pdf for comparison purposes.
