Is my modem properly provisioned?

I recently upgraded my internet service from the 1.2 Gig tier to the 2 Gig tier. My account shows 2 Gig / 250 Mbps service. My (customer-owned) modem is locking upstream channels only up to 36 MHz, indicating low-split plant. My upload caps at ~40 Mbps and download caps at ~1.13 Gbps. This indicates to me that I'm still on the 1.2 Gig tier. Please confirm whether my node is upgraded to mid-split and whether customer-owned modems are eligible for the 2G enhanced profile.
