Graded card review question

So I’m thinking about sending a PSA 10 to Beckett to see if it’s eligible for a pristine 10 or possibly even if I hit the lottery a black label but on the website when you try to do it it says minimum grade accepted 9.5 and I don’t want it to be sent back in a 9.5 so does anyone have any idea how I could send in a PSA 10 but they will send it back if it does not great at least a pristine ton. Any info would be awesome or tips
