Is the Hitron CODA5719 compatible with Xfinity even though it is not on their approved modem list?

Recently, I noticed that Xfinity added the Hitron CODA5610Q to their approved modem list, which is great news. However, I currently own a Hitron CODA5719, which looks almost identical to the CODA5610Q but has some technical differences. The CODA5719 has a faster processor and more RAM than the CODA5610Q, making it capable of handling more demanding tasks and providing faster wireless speeds. However, the CODA5719 is also more expensive than the CODA5610Q.

Both modems have the same DOCSIS capabilities, supporting both 3.0 and 3.1. The only difference is that the CODA-5610 supports a software switchable 5-42MHz / 5-85MHz return path, while the CODA-5719 supports a software switchable 5-85MHz / 5-204MHz return path.

When I tried to activate my modem using the Xfinity app, I received a message stating that I am using an unapproved modem from their list. However, I have screenshots showing that the modem is registered in the Xfinity network, and I also received an activation page with a public IP address.

Can someone please clarify if the Hitron CODA5719 can be used with Xfinity, even though it is not currently on their approved modem list?
