Have you accidently set colour mode ll which will set the colour space to Adobe RGB? Your computer software will by default be set up for sRGB and will cause Adobe RGB pictures to display and print with a compressed range of colour.
You will find much discussion about the relative merits of sRGB and Adobe RGB. What is not open to discussion is that the camera and the rest of your equipment must all use the same colour space. Print kiosks normally expect sRGB.
