Here are examples I would consider actual infill, on Main St Vancouver, because it filled gaps and forms part of the existing streetscape. Infill is determined more by context, than by the development type itself.

But if you turn the camera around to look at the other side of the street, I wouldn't consider that infill, but just standard midrise development, because it was all new development and not filling in any gaps.
I would just include the words "
Infill & Midrise Construction" in the title to make it more accurate.
