I post-processed a RAW photo in Photoshop in 16bit in the ProPhoto color space and lastly exported it to an 8bit sRGB JPEG image.
Now the funny thing is that I experience different results depending on where I view the image. I use Windows 10. Photos, Firefox, Internet Explorer and Photoshop show different results.
In Photoshop and Firefox the JPEG looks like it should look - but in Photos and Internet Explorer it looks heavily over-saturated relative to my editing experience in Photoshop.
Why is that?
I am concerned that my image is not displayed consistently across software or devices. I know there is some display variation due to missing calibration, device fidelity and ambient light, but not this extreme.
Note that I am using a calibrated wide-gamut EIZO monitor (calibrated using Color Navigator and the Datacolor Spyder 5 Pro with the Photography preset).
And a comparison between Firefox and Edge rendering:
