Confirmed with

Version: 7.5.0.0.alpha0+ / LibreOffice Community
Build ID: 61f5c991a97de8990badfed6ef840941b5aa8c7f
CPU threads: 12; OS: Linux 5.15; UI render: default; VCL: kf5 (cairo+xcb)

The equation has color in the PPTX file and it is not being imported when opened in Impress.

This looked fine until 6.4.0.3, but probably due to the replacement image shown, as described in bug 129061 comment 5.

Indeed this "worked" in the past due to duplication.

However, since here we only have a single Formula object, we could fix this in the import filter.
