This is observed with lualatex in TL18 and hyperref 2018/09/30 v6.88a.
When hyperref is loaded the PDF creator field in the produced PDF
contains "LuaTeX-1.7.0" whereas LuaTeX says about itself it's "1.07.0".
Without hyperref the creator field says (correctly?) "LuaTeX-1.07.0".
MWE to reproduce:
Loading hyperref with option [luatex] doesn't change anything.
