There is no bleed.
In your screenshot the green lines at the edge denote Trim size.
If there were bleed you would have a red border within the area.
To check bleed, other than the visual.
From the Pages Panel choose Crop Pages
Check the values for Crop, Art, Trim, Bleed
They will all be zero
There should be a predefined Preflight check but I cannot find one. I wonder if one could be created...
