Yes and it works very well on those sports channels. TNT has been expanded to cover all their sport as far as I can see this season which wasn't the case last season.
The exceptions are the two part time Sky Sports UHD channels [albeit the sport on them is on another channel in HD], Sky Racing, and of course the channels / sport not on the EPG.
If you going to use it, choose the channel from the EPG and you can go straight to the start, and it is quick then to go forward to kick-off if that is what you want to do. If you change to a live channel directly, of course you see the current score before going back to the start, so try to remember not to do that.
The delayed start goes back as far as a week.
If important to you, note that the UHD sports channels don't carry Dolby Atmos on Stream, unlike the V6.
[Note you've posted in the TV on the Go section rather than the Stream section, but from what you have posted, I assume you are talking about the latter].
