Is there a chance Unity profiler does not show memory leak but the exe/app actually leaks ? (Windows standalone)

We have a game where Profiler doesn’t indicate memory leak. But external exe tracking shows memory growth.
So is there a chance Unity profiler doesn’t show memory leak ? or
Does Unity Profiler have a blind spot ?

Unity 2017.4.26f1
Windows Standalone

Is there a chance that the memory grows because you simply load more and more assets into the memory? Unity has a dedicated Memory Profiler, you can try checking that
