Gradient fill in 3D graph data series does not show properly when published to PDF or EMF image

Hi team,
We noticed the issue when EMF image is created and PDF is published from Excel 3-D graph
with gradient fill in data series.
The gradient fill colors do not have same look and fill as in the input Excel graph.
Attached is zip archive illustrating the issue, it contains:

  • test3D.docx - input excel template with 3D graph named range “Chart1”;
  • test3D.xlsx-v24.10.0.emf - output EMF image;
  • test3DChart1-v24.10.0.pdf - output after save as PDF;
  • Gradient_glow_in_PDF_vs_Excel.png - comparison between input Excel and output PDF, illustrating the issue;
  • TestEMFImageAndPdfFromExcelRange.java - sample test program to reproduce the issue

This issue occurs under both Linux 7 and Windows 11 OS.
Are there any options that can be applied so the output gradient fill in EMF image and PDF would match input Excel graph?

Please let us know, if you need additional information.
Thank you.
