I believe the issue is related to the color profile of the monitor, could you try changing it to sRGB IEC61966-2.1 in the color management and let us know how it goes?
Click start and open Control Panel.
In the upper right corner type in [Color Management] into the search bar and click on it.
Then click on [Add] and find the line titled sRGB IEC61966-2.1 and set it as default.
Then relaunch Lightroom and let us know if it helps.
The Windows 10 Photo App is not color managed, so it can indeed show photos with different colors than in Lightroom. You shouldn't use it for critical work.
Yes, you do need to calibrate your monitor properly if color fidelity is important to you.
But the bottom line is when someone else views the photos on some other computer, you have no control over the software they use (although you can suggest what software to use), and you have no control over whether or not their monitor is calibrated, and so basically there's little you can do to ensure that the colors will appear the same on someone else's computer.
Thank you very much Sahill, that seems to have done the trick, much appreciated
Thank you for your input, i will look into getting the monitor calibrated.
Glad we got it working! Feel free to reach out to us for any future queries.
I find it hard to believe that setting the monitor profile to sRGB fixed the over saturation in the Photos app, since it doesn't use the monitor profile, and should display the same, regardless of what the monitor profile is set to.
Since you have a wide gamut monitor, you have to avoid using non-color managed applications like Photos – they will always display wrong, and typically over saturated.
The Windows Photo Viewer is color managed, as is Adobe Bridge. Irfanview is a free, color managed image viewer, but you have to enable color management in Settings. If you don't mind paying a little money, I can recommend ACDSee.
