Color and lighting shift after export to jpeg

With colour management we can only set our own devices, hope others do the same, but send images with a safe default.

So, we calibrate and profile our computer screens (using a hardware colorimeter) to ensure we are adjusting our images on a device that is displaying correctly. When interchanging images with others that do the same and have their software set up to use the embedded profile, all we need to do to ensure they see the same as we do is embed the image profile.

However, when we send images into the world of uncalibrated and unprofiled displays, all we can do is use appropriate image settings e.g. convert to the sRGB colour space and ensure the sRGB profile is embedded with the image.

If the recipient is using calibrated and profiled displays all is good. But, on other devices, such as phones, things get a bit 'wild west.'  Some devices/software do read the colour profile and display close to correctly. Others ignore it altogether.  If those that ignore it have a display that is close to sRGB it will still look close to correct.

The scenario you describe of an oversaturated image view happens when the device has a wide gamut display but is ignoring the image profile of sRGB. What you do not want to do is adjust the image itself to look good on such a device, as it will be guaranteed to look incorrect on other devices.

When you export, make sure you both convert to sRGB and embed the colour profile.  After that it is out of your control.
