Edit in photoshp from lightroom is resulting on changes on the lumnosity after saving

No, there is no need for Lightroom and Photoshop color settings to match, that is a common misunderstanding. Any incoming profile will be treated correctly in Photoshop. That profile will override the PS working space.

Most likely this is a defective monitor profile. While both these files end up in the same monitor profile, the source profiles are different. That means the conversion, the actual math, is different. If the profile isn't written to correct icc spec, that conversion may just work in one, but fail in the other.

A difference such as this is usually a red flag for a defect monitor profile.

Are you using a calibrator to make your monitor profiles? If so, run it again, and make sure it's set to make version 2, matrix-based profiles. Version 4 and LUT (table)-based profiles are prone to errors in some configurations.

If you're not using a calibrator, you should have one. Until then, use a standard profile that is close to the monitor's native response. Depending on the type of monitor, that would be sRGB IEC61966-2.1, Adobe RGB or Image P3/Display P3.

Without a calibrator, you'll usually get generic manufacturer profiles distributed through Windows Update, and these profiles are surprisingly often defective in various ways.

Here are a few things you can check and try to resolve this issue:

1. Color Settings Consistency: Ensure that your color settings are consistent between Photoshop and Lightroom. In Photoshop, go to Edit > Color Settings and check that the RGB Working Space matches what you're using in Lightroom. Adobe RGB (1998) or sRGB IEC61966-2.1 are commonly used profiles.

2. Monitor Calibration: Sometimes, the way colors are displayed can be affected by how your monitor is calibrated. Make sure your monitor is calibrated to a standard profile to ensure color accuracy across different applications.

3. Bit Depth Differences: Check if there's a difference in the bit depth settings between Lightroom and Photoshop. Lightroom works with 16-bit images by default, which allows for more color data. Ensure Photoshop is set to handle 16-bit images as well by going to Image > Mode > 16 Bits/Channel.

4. Soft Proofing: Use the soft proofing feature in Photoshop to see how your colors will look under different lighting conditions or on different devices. You can activate this by going to View > Proof Setup and selecting your desired profile.

5. Profile Corruption: Sometimes, resetting Photoshop settings isn't enough if the color profile files themselves are corrupted. You might need to reinstall the color profiles or Photoshop itself.

6. Direct Transfer Check: If you're using the 'Edit In' option from Lightroom to Photoshop (Photo > Edit In > Edit in Adobe Photoshop), ensure that you are transferring all the adjustments properly. Check the 'Edit with Lightroom Adjustments' option if prompted, to ensure all your edits are carried over.

Try these steps and see if the issue persists. Color management can be quite tricky, but ensuring consistency across your workflow is key to maintaining the integrity of your images.
