Sure it does. Without luatex85 is simply quits and does nothing at

Package cmap Warning: pdftex not detected - exiting.

With luatex85 it inserts cmaps into the pdf. You then see messages


and the pdf contains e.g. 

%!PS-Adobe-3.0 Resource-CMap
%%DocumentNeededResources: ProcSet (CIDInit)
%%IncludeResource: ProcSet (CIDInit)
%%BeginResource: CMap (TeX-OT1-0)
%%Title: (TeX-OT1-0 TeX OT1 0)
%%Version: 1.000

But the behaviour imho shouldn't depend on luatex85:

If you want the cmaps then it should do it also without luatex85,
and if you don't want them it should exist also with luatex85.
