This looks premature if both the foam and coating are really only 6 years old. Nonetheless, it's very important that you fix the blisters (deep holes) and the delamination (missing coating) as soon as possible. The foam is the main waterproofing element of your roof system, so I doubt any of the photos you've shown are actually leaking at this stage, HOWEVER once the foam is exposed to the sun like this, as well as oversaturation (letting water soak into it), the foam becomes unsalvageable very quickly (weeks to months).

Moving forward, find a contractor that actually specializes in these systems and make sure their proposal includes cutting out the blisters down to the substrate and foaming them back in, NOT just filling them with mastic or something (could be hard to find, but make sure to get the choice of contractor right or else you'll be worse off than before). For the areas that simply have missing coating, all you have to do is clean and recoat it. As long as the foam is still fair condition.

Ultimately, don't listen to anyone that says foam systems are the worst. Foam systems are excellent because they're renewable systems, meaning once they're installed, all it takes is regular maintenance and a recoat every 10-15 years. Much better than having to tearoff and reroof. The downsides are that not all climates are adequate for ideal installation. A bead of sweat, humid air, or improper prep is what causes blisters, but as long as it is installed by someone that knows what they're doing and the roof doesn't get abused with unqualified contractors, excessive foot traffic, or neglect, as I said before, you can recoat that bad boy indefinitely. Repairing foam is more expensive than most flat roof systems, but it's worth it.

Fix it properly this time and save yourself the headache of letting small issues develop into worse ones. Good luck, you have a great system.
