I didn't notice if you said you washed the walls down first before installing the thinset. This is a crucial step, especially on cbu. Even if your thinset is mixed properly, it can make for a bad bond. CBU is REALLY thirsty, and can dry the thinset out way too fast...dried thinset doesn't bond well, cement needs moisture to hydrate and cure. Cement grows interlocking crystals when it has enough moisture to cure, and this is what makes the bond...not enough moisture, poor bond.
All membranes must pass a bonding test and the number is 50psi, and tests show 75psi is typical on Kerdi and Ditra AFTER it has fully cured (industry standards are after 28-days for ANY mortar, this is not specific to Kerdi or Schluter). There's more than enough strength to start to lay tile on Ditra immediately after embedding it, and Kerdi as well. For maybe as long as a week, if you catch an edge, and try to peel it back, it will come off, usually tearing a bunch of the fleece off in the process, but it will come off. So, catching an edge with a vacuum, depending on how you caught it and how you moved it, how long it has been on the wall, and, obviously, the strength of the vacuum, you could damage the install further.
In the example John showed of a poorly installed shower, it was obvious that they did not get good bond on the membrane. That is why it is critical to peel back the sheet to check occasionally to verify both the surface and the membrane are fully covered...you should not be able to see any of the membrane, and the wall should be covered with thinset, if it is done properly.
Most of the time, when you embed the membrane, it ends up a bit sloppier on the surface because you run from the middle to the edge, and this pushes any extra thinset out of the seam. Your seams are pretty, but you may not have embedded things well, and may have excess thinset there. For certain, you don't want lumps, but neatness isn't particularly critical here...getting the membrane bonded well is, and that tends to be not what I see.
Only way to be certain is to have someone look at it that knows and understands it well. It's hard to do from pictures.
