The brick wall is f4.9 - that is enough to cause softening by diffraction on this size sensor and the effect will be visible viewed at 100%.
There is a table in the following link that shows your sensor needs to be f4 to create a sharp A4 print.

I reckon if you re-shoot the brick wall at f2 you will get better results at 100% (the bke shot is f2).
This assumes the center of your lens is OK wide open (probably true).
At f2 the edges of the image might look rubbish at 100%, but the center should look noticably crisper.
In short, re-test using:
- lowest ISO
- widest aperture
- self timer
- tripod
- stabilisation OFF
and only check the center of the frame at 100%
Then start using smaller apertures checking the edges of the frame to find out the lenses sweet spot.
Then turn the IS back on and try hand-holding to see what shutter speeds you can get away with.
Pixel peeping is bad for your sanity
