instruments stack trace unity frame work

I am looking for unknown memory
Because my game memory is 1.1gb in Unity Profiler, but about 1.8gb in the actual build.

As a result of profiling in both android and ios

here was a little difference

maybe called a android : unknown memory
ios: anonymous VM

I thought to use instruments that can see the memory stack trace, and I tried profiling, but only the address value was found in the unity-related part, and I couldn't find the C# script name or method name.

How can I check?

ps. my build setting
[strip symbols during copy : no]
[debug information format : dwarf with dsym file]
