Why do JPEGs show a purple cast in Lightroom but look normal elsewhere?

On a new Windows 10 installation, JPEG files from an older camera display with a strong purple cast in Lightroom, while the same files look normal in Photoshop and Windows Photo Viewer. Photoshop also warns that the monitor profile ("Samsung Natural Color Pro 1.0 ICM") appears to be defective. Could this be a Lightroom issue, or is it related to monitor/color management settings in Windows? How can it be fixed?

This usually occurs due to improper OS-level color management setting. Following these instructions will fix it:
Windows
- Close Lightroom.
- Go to Start menu > Control Panel > Color Management.
- Click the Devices tab if it’s not already selected.
- From the Device pop-up, select your monitor. If you have more than 1 monitor connected, pressing the Identify monitors button will display a large number on screen for identification.
- Check the ‘Use my settings for this device’ checkbox.
- Make a note of the currently selected profile, which is marked as (default). If there isn’t an existing profile, you can skip this step.
- Click the Add button.
- In the Associate Color Profile dialog, select sRGB IE61966-2.1 (sRGB Color Space Profile.icm) and press OK.
- Back in the Color Management dialog, select the sRGB profile and click Set as Default Profile, and then close the dialog.
Mac OS X
- Close Lightroom.
- Go to System Preferences > Display.
- Select the Color tab.
- Press the Calibrate button and follow the instructions.
- Turn on the Expert Options and calibrate to gamma 2.2.

This is most likely not a JPEG or camera problem. It’s usually caused by a bad or corrupted monitor ICC/ICM color profile in Windows.
Lightroom relies heavily on color-managed display output, so a defective monitor profile can cause strong color shifts like a purple cast. Photoshop’s warning about the Samsung monitor profile strongly supports that.
Fix:
- Close Lightroom.
- In Windows, open Control Panel > Color Management.
- Select your monitor under the Devices tab.
- Check “Use my settings for this device.”
- Add and set sRGB IEC61966-2.1 as the default profile.
- Reopen Lightroom and check the images again.
If that solves it, the original monitor profile was the issue. You can later recalibrate the display and install a fresh, valid monitor profile if needed.
So: Lightroom is likely displaying the files correctly through a broken monitor profile, while other apps may be ignoring or handling that profile differently.
