Embedded Grayscale Image Inverts When Unembedded from Illustrator 29.8.1 and Opened in Photoshop
I’m encountering a consistent issue with Adobe Illustrator version 29.8.1 on Windows 10 (64-bit) involving grayscale images.
When I unembed a grayscale image from an Illustrator file and open it in Photoshop, the image appears inverted (as a negative — colors reversed). This only occurs when the embedded image is in grayscale mode. Color images do not seem to exhibit this problem.
This behavior did not occur in previous versions of Illustrator and seems to be specific to version 29.8.1.
Steps to Reproduce:
Open an Illustrator file (v29.8.1) with an embedded grayscale image.
Unembed the image.
Open the resulting file in Photoshop.
Observe that the image is displayed with inverted (negative) colors.
This issue is interrupting my workflow, especially when working with grayscale assets. I would appreciate your assistance in identifying a fix or workaround, or confirmation if this is a known issue under investigation.
Please let me know if you require further information or sample files for troubleshooting.
Thank you for your support.

There are several similar problems on the topic:
1. 1 bit TIFF files still importing inverted after all these years — http://illustrator.uservoice.com/forums/601447/suggestions/41619745
2. PDF with CMYK JPEG is inverted when opened in Illustrator — http://illustrator.uservoice.com/forums/601447/suggestions/38271577
3. Illustrator turning all PNGs into negatives (with or without yellow background) after saving and reopening document — http://illustrator.uservoice.com/forums/601447/suggestions/45228802 (marked as fixed)
...and others -
Can’t reproduce this following the steps — the image opens non-inverted.
Perhaps something differs... Please share a test file with the embedded image that leads to this behavior.
