No expert but looks like powdery mildew on your leaves? I also have some of this on my laurels and had assumed it was that as I have other plants affected.
I would also say the holes are caterpillar damage rather than shothole simply because I had the same on my laurel last year and took in a leaf specimen to garden centre and they said it was that.
Neither is serious in my understanding.
