31/32 Downstream Channels Bonded with Gig Plan?

Just wanted to ask here. I recently upgraded from the 800Mbps Superfast plan to the 1Gbps plan.

I have a CM1000v2, which I've been "told" needed to be upgraded although per the hardware specs should be able to handle speeds of 1Gbps. A few questions:

• In my cable modem connection status, I see 31/32 Downstream Bonded Channels with Channel 32 being not locked (screenshot below). Since I supposedly have the 1Gbps plan, shouldn't Channel 32 be locked? I was under the impression that plans or speeds under 1Gbps would not have that channel locked. Just to be sure I'm getting what I'm paying for I physically connected a laptop to the cable modem itself and I am getting download speeds of 940Mbps and which I also think the throughput max of the CM1000v2 stated was ~950Mbps or so. I have not experienced any connectivity issues, but should Channel 32 need to be locked given that I am on Gig plan for full functionality?

  

• I live in Franklin, TN. I thought the Gig tiered internet plans offered higher upload speeds. I'm still being capped at a max of 20Mbps upload per my plan - is this correct or is it my modem? All of my previous lower speed plans in the past always maxed out at 20Mbps upload.
