I generally use an online service. The offer the option of "enhanced" or "no effects". No effects mean they leave it as uploaded.  I do that and all is well.

At a local durgstore printing kiosk,  I got very good results from their Fuji printers. I did ask that no enhancements be done and all came back quite well.  Another store of the same chain name was tried and the images were a bit washed out.  I learned their equipment was not so up to date as at the other store branch and the people there did not know how to calibrate things in the first place. The store will good results had reasonably knowledgeable personnel doing the printing.

This is often a live and learn thing when using printing services. Ask for no adjustments or enhancements in your printing, if that is what you want.   At one online service, I asked how to make certain I got the best from what I uploaded. They suggested a few trials on things such as bightness and contrast levels and sharpness on my end, then to use my settings producing the best results.  I do that and again am quite satisfied with the prints being true to what I want.  Actually, close to the very same of every adjustment I use is the same as for web...except image size(largest files to printer) and sometimes sharpness adjustment.        Tom
