Is there any chance you don't have SET PROCESS/PARSE_STYLE=EXTENDED set?
That setting is required in order to maintain the case of the command
line. Without it, quotes are still needed.
I've had extended parsing as a permanent setting for over 2 decades,
since the V7.2 days, so I sometimes forget that not everyone uses it.
I get:
$ gs -dNOPAUSE -dBATCH -sDEVICE=ps2write -sOutputFile=out.ps -fOUT.PDF
