Don't think so.

Save/restore information for QSYS.LIB objects is stored in the  
object's OIR which is part of the *LIB object.

Stream files don't have an OIR (or not one I can find) therefore no  
save/restore information.

A DMPOBJ of a *PGM shows a .SAVE/RESTORE. section.

A DMP of a stream file does not therefore I presume this information  
is not tracked.

When a stream file object is changed the Change date is updated and  
the Archive flag is turned on. When a stream file object is saved the  
archive flag is turned off (if UPDHST(*YES  | *SYS) is specified).

The SAV command does allow a 'sort-of' SAVCHGOBJ function via the  
CHGPERIOD keyword. This supports a special start point of *LASTSAVE.  
As far as I can tell this just means all stream file objects that  
have their archive flag set on.

I note that the attribute flags don't appear to be in the dump either  
so it's possible that the system does track the save date information  
but simply doesn't expose it. However, the observed behaviour is  
consistent with the Archive flag being set or unset.
