Psd profile conversion bug (jpg & tif ok)

[stroker]

I have three grayscale images with a grayscale profile "Dot grain 20%". The formats are JPEG, TIFF AND PSD.
Shouldn't I get the same output image when converting the colorspace to RGB using a RGB profile?

Code: Select all

convert image.jpg -intent relative -black-point-compensation -profile AdobeRGB1998.icc new.jpg
convert image.tif -intent relative -black-point-compensation -profile AdobeRGB1998.icc new.jpg
convert image.psd -intent relative -black-point-compensation -profile AdobeRGB1998.icc new.jpg

The first two command generates an image with embedded Adobe RGB profile. The last command (psd) still has "Dot grain 20% profile".
