Not so you'd notice!

It depends rather on the wall finish and the care and skill of the
contractor.

The flats opposite me have a rendered finish and the infill dots are
noticeable, but not terribly intrusive.

In a brick wall with regular mortar lines and a variation in brick colour
making matching the colour more difficult, the holes would be much more
noticeable.

When we had ours done I asked them to fill the holes with a matching
'mortar' (the original was red, we pointed with mastic sand when we moved
in). They said that they couldn't so they knocked quite a sum off the bill
so that we could do it ourselves. We never got round to it and the other
week I was looking for the holes - which they filled with ordinary mortar.
It took a long time to find them - to my surprise.

Probably still worth doing though, for economy and comfort, and the added
value of the insulation to the house price would more than offset the
slight detraction in exterior appearance (unless, of course, the house is
particularly delightful to start with).

Oh absolutely, I couldn't agree more. the visual impact is very small and
could be resolved if it were thought necessary.
