Hi, i see a big difference in exposure on all my catalogs. I am running ligthroom on Windows 11. The Profile of the monitor is set to sRGB IEC61966-2.1, i also use it for export the files. Please see the screenshot of the windows image viewer! (Left image viewer / rigth LR) Also on mobile devices the pictures are brigther than in LR it self. I couldnt find any setting fixing this issue!
The Windows Photos app is now color managed (provided that your Windows is up to date), and should display the same as Lightroom. But color management in Windows 11 is broken, and this seems to affect Adobe applications in particular. My guess is that Photos is displaying correct colors. The only known solution is to downgrade to Windows 10.
