That's probably related to SIP.  See the following post from Jonathan
Perkin for more info:

  https://mail-index.netbsd.org/tech-pkg/2020/02/17/msg022645.html

In particular, Jonathan writes:

  SIP does not disable DYLD_LIBRARY_PATH, it only ignores it for
  binaries *that are protected by SIP*.  Nothing built by pkgsrc is
  protected by SIP.

You might get around your problem by using a shell from pkgsrc.  For
example, here's a comparison of /bin/sh and /opt/pkg/bin/mksh using
echo:

----
$ DYLD_LIBRARY_PATH=foo /bin/sh -c 'echo $DYLD_LIBRARY_PATH'

$ DYLD_LIBRARY_PATH=foo /opt/pkg/bin/mksh -c 'echo $DYLD_LIBRARY_PATH'
foo
----

However, as Jonathan wrote, SIP is actually ignoring DYLD_LIBRARY_PATH
for binaries that are protected by SIP, so even if you use a shell from
pkgsrc (that is not protected by SIP) but then use a protected binary
from the macOS system such as /usr/bin/env (like you may have been
trying to use in your test), DYLD_LIBRARY_PATH will still be ignored:

----
$ DYLD_LIBRARY_PATH=foo /opt/pkg/bin/mksh -c '/usr/bin/env' | fgrep DYLD
$ MY_VAR=foo /opt/pkg/bin/mksh -c '/usr/bin/env' | fgrep MY_VAR
MY_VAR=foo
