You are worrying me that either the fuel is getting worse or something else is going on.
Mine never looked like that in my 2011. I changed between 10k and 15k miles. I erred on the side of 10k miles because a diesel tech told me that, that is what he does in his. I haven't hit 10k miles on my 2015 yet and doubt I will for a minimum of several more months. Although I may check them the next time I am near the truck.
I would keep the 10k mile change interval - and it does appear that they are doing their job.

Mine have been quite consistantly that dirty. That was one of the reasons I added the Dieselsite system. I fill up the truck everyday and I don't know if that makes for more contaminants or not. I have never gone more than 10K miles between changes.

That primary filter is typical of what I see. The filter is doing it's job. If your filters begin to get that hour glass shape then you should consider reducing you service interval but otherwise I see no reason to be concerned.

I did mine yesterday at 24,000 miles and they looked better than that. I also have the Dieselsite filters. Looks like they are doing a fine job of keeping things clean.

The top two filters in his photo are the Dieselsite filters.

THAT is the important one to look at because that is your LAST line of defense before the fuel gets to the injectors....
Just my humble opinion of course.
I don't change my filters but once a year and of course this time I skipped a year because I traded in... Sorry I forgot what the difference filters look like. I thought the top picture was of a couple of upper fuel filters...
There is always next time - as you pointed out.
