ULNS systems typically do best with a lower dkh, around 7. However, mine has been above 10 for months running zeo with no ill effects. Not a really important value, other than stability. If yours is 11 and stays there, you shouldn't have a problem. A noted issue with high alk and ULNS is tips burning, but that doesn't sound like the issue you're having.

Well, we're still not sure that no polyps is bad. But by my statement, I mean other than no polyps, my colors are great, growth is as expected and none of my SPS went white
Previous tanks ran with alk above 11 or 12 for years, no issues (again, other than PE).

This is more what I was getting at before. whether you are intentionally ULNS or not, high alk with low nutrients can cause tip burn in acros and I have found it to cause birdsnests to die from the inside out. So if you're doing a good job at keeping nutreints low, well then alk might be an instigator of this.
