I recommend that you contact Shaw, and get the details directly from them.

Which TV box(es) do you have?
Shaw lets you have multiple BlueCurve boxes on one account, or multiple "non-BlueCurve" boxes on one account, but not a "mix" of BC/non-BC boxes on one account. They will force you to have 2 accounts, if you want to have a "mix".
I run 2 4k wireless boxes at the moment. I asked to get a coaxial plug in 4k box but those don't work this year. I had it last season on that box. I was told will not work on either 4k boxes this season why?
I wouldn't even think any of the NHL Centre Ice channels are broadcasting it's games in 4K yet. I don't know why the broadcast wouldn't work on Shaw's 4K boxes, pending the channel is available to watch, as Shaw hasn't made any 4K channels available yet.
It is only the wireless BlueCurve Xi6 boxes that will not work for Centre Ice, because of “technical restrictions.”
