Is there any chance Google search would not show all the backlinks unlike WMT?
That has always been the case. In the beginning of Google, they only showed links over PR4. Then they changed and began showing a random sampling of links, and that's what they do today. Not only that, but the specific sampling of links they show publicly changes from time to time.
So we can't draw any conclusions from what we see with the link: operator searches.
