Upgraded to 400Mbs from 100 . Very little change in download Speed test results

This past Monday I upgraded my plan to 400. I also upgraded the Modem to MB7621 as the old one was 4 years old and 16x4. As of this morning the download speed has increased from 68 to 95. This result is on my PC

It could be that Comcast has not upgraded the speed profile yet but I thought that would happen within a few hours.  The new Modem shows 24 bonded channels connected vs 16 for the old one. Upstream is still 4 and I suspect that only gets bumped if I go to the next level of 1Gbps. I'm not concerned with this but any ideas to try to address the download speed is appreciated
