Summary0014191: PDF/x-3, PDF/x-4 can not be converted to output color RGB->CMYK
DescriptionScribus help say:

https://www.scribus.net/svn/Scribus/trunk/Scribus/doc/en/pdfx3.html

PDF/X-3 is based on PDF 1.3 and requires ICC color profiles to be resident in the PDF. This allows for RGB colors to be used in the PDF, as these will be converted to CMYK using ICC profiles as late as possible in the printing process.

PDF/X-4 is based on PDF 1.4 and allows for using a major PDF 1.4 feature – transparency – in a PDF/X file. PDF/X versions prior to X-4 do not support transparency. Support for PDF/X-4 will be added in future Scribus versions and is already in testing.

PDF/x-3, PDF/x-4 can not be converted to output color RGB to CMYK. If the input image RGB color, image output RGB color!

This problem!
There should be a possibility purely CMYK output production! Othervise is made from mixed PDF (RGB and CMYK). If the printing-house did not pay attention, the end result will be ugly (unfortunately, I know from experience)!

CMYK PDF is always a good result.

PDF/X-1a often is not a solution e.g Managing gradients.

Confirmed. It's fixed by converting the files with Ghoscript with the -sColorConversionStrategyForImages=CMYK parameter

This bug offered me the baddest burst-up I had with a printer ever.
the two attached files show the printer report before and after converting with Ghostscipt.
