Filed an issue on DSpace issue tracker for the filter-media bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: DS-3516
Discovered that the ImageMagic filter-media plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
Interestingly, it seems DSpace 4.x’ s thumbnails were sRGB, but forcing regeneration using DSpace 5.x’ s ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see 10568⁄ 51999):
