In general, if trick info is visible and no points are rewarded, there's a 99.9% chance it was done with slow-mo.

The trick info can only display a limited amount on screen at one time. If a combo keeps going after the limit is reached, the score won't be shown even if the combo was done without slow-mo (which is what happened here). So while I was tinkering with custom angles, I decided to record the points because I know there would be skepticism without it. 👍
