Cameo is the contrast between the devices (raised portions) and the fields (flat portions). A brilliant coin will have little to none, a cameo coin will be clearly contrasted, and a deep cameo will be very contrasted. There should be few to no breaks (brilliant patches) on the devices in order to achieve the cameo designation, and no breaks at all to receive DCAM. In addition to the degree of "frost" on the devices, the depth (blackness) of the mirrors plays an important role
its almost impossible determining the difference from just a photo. one way to see if you're in the ballpark first you need to remove the coin from the holder. you would need to set the coin on end with newsprint under it so that its reflecting onto the face of the coin. make a line or mark 6" from the coin on the newsprint. If you can read the newsprint reflected in the fields from a distance of 6" you have a DMPL coin. (BTW both sides must make this mark to receive the designation)
your coin is at least CAM due to the frost surfaces. notice muddlers coin. the fields are extremely clean with no type of disruption in the surfaces. your photos are showing marks throughout. this could be from the holder or lighting. its hard to tell. if its on the coin then you can rule out DCAM. this is where you would need to rotate the coin to determine that
its also very difficult to get a good photo due to the reflective mirror like surfaces so this might be something you need to do at home with the coin in hand.as you can see its not straight forward and difficult to assess by photo.
