The Blue Jays are one of 11 teams to have trackman camera’s set up in their home ball park during Spring Training. Those cameras can provide meaningful data, even halfway through Spring Training.

At this stage hitters don’t have that many at bats/batted balls so there isn’t much to take away from those numbers.

If a pitcher has increased their spin rate, this is likely a meaningful change and something they have worked on, either with a new grip/finger placement or are using a sticky substance.
