I have had no issue with SIP/White not taking out compounding marks. After that step I am very confident the holograms etc. have been removed -not hidden. Follow up with PO106FF/FA or 85RD to refine the finish even more.
Sounds like you are using to mild of a product to take out the compounding marks and it's just masking the defects. I've seen it so it's very possible.
