Cellphones differ vastly compared to Traditional landlines using PSTN technology. With a Traditionally Analog Telephone, there is no verify message, the phone was built to a spec/standard that is used around the world and there will never be any enhancements to this spec to incorporate new technologies.
Rogers home phone though its VoIP based, it still has a limitation of how to display messages on the handset other than the caller ID, they could easily add some kind of beep sound when you pick it up to notify you, or put some special symbol or character in the Caller ID name, or simply just do nothing and leave it alone, so the verification is done but nothing will notify you the end user
Cellphones on the other hand, especially ones that use more newer technologies (4G and newer), can be upgraded via back end enhancements on the network side and on the phones firmware itself to introduce newer calling enhancements relatively easy.
For the Verified Caller checkmark or symbol to appear, there must be both upgrades done on the backend network, as well at the handset level. So far reading this post, it appears the upgrades might be done on the back end systems only at this time with the exception of Google Pixel, so its just a matter of them working with the handset makers to have the software/firmware gradually rolled out soon.
