Photo Quality Loss - Does Box Compress Photographs

I’ve been uploading high quality photos into Box to share with our communications team and I am noticing that the quality of the photographs are less than ideal after uploading. I’ve edited the photographs on calibrated monitors and have displayed the images across various monitors with not noticeable variations. When these photographs are uploaded to Box, there are artifacts present within the images and the colors seem to be drab and muted. I’ve never experienced this issue with other platforms and I am inquiring if Box compresses the photographs, stripping the photos of color profiles to just provide viewing images?
