Looks like you are right.

I OP has an ASR1002-X, check one here:

#show ver | inc mem
cisco ASR1002-X (2RU-X) processor (revision 2KP) with 3729028K/6147K
bytes of memory.
8388608K bytes of physical memory.

^ This only has 8GB of RAM and it is using roughly half as expected.

Although not using half isn't exactly a bad sign in its self, the
Linux virtual memory manager allows for memory overcommit:

#show platform software status control-processor
Memory (kb): healthy
  Total: 8091848
  Used: 3885636 (48%)
  Free: 4206212 (52%)
  Committed: 5328504 (66%), status: healthy, under 95%

So it maybe that IOSd on OP's system would simply grow more when needed?
