K5 Dust Image

Here is an image shot with my K5 at F22 showing the dust spot. I have tried blowing it with large Rocket Blower dozens of time. Tried the built in dust removal dozens of times. Yet it never ever shows up on my dust alert feature. the image is pure white no matter how much you enlarge it. thought for sure you would see it on the dust alert.

I get spots like this on my K-x that don't show up in Dust Alert either. A wet cleaning has always taken care of them. In fact, I'm due for one now.

This shot is at ƒ/22, can you show an example at ƒ/3.5 or something closer to wide open?

I'm asking because at ƒ/22, you may even see dust stuck on the lens, but you probably wouldn't at ƒ/3.5.
