Upgraded to 1 Gig up/down symmetrical plan. Can someone confirm if my location is actually FDX or mid-split. Could be a mistake

Two days ago 1 Gig up/down symmetrical and all other symmetrical plans populated the internet plans page for my address
Signed up for 1 Gig up/down today. Was given an XB8 at xfinity store. As I understand it, XB10 modem is required for symmetrical up/down plans
Currently seeing 1000/100 mbps speedtest

Before running down an XB10 modem, can someone confirm my location actually upgraded to FDX or is still on mid-split

I already spent an hour w/ chat support basically telling me everything looks fine. They ran a speedtest at the gateway which showed 1gbps which checked off their boxes, but that only showed download speed by the looks of it.

If the symmetrical plans offered for my address was a mistake, I'd like to know before taking this further
