I've been using Lightroom for years but have recently started having issues with exporting images. When I export from my Macbook, they look great and how I expect them to look. I've checked my Mac's screen calibration and it is in srgb display (calibrated) so should look the same.
But when exporting (JPG, PNG, all types) and then send to my iPhone for publishing on Instagram, the images are desaturated and less contrasted. The images look fine when exported on my Mac desktop so I feel the display must be the issue but I can't work out how to fix this issue.
