Correct.

Sigh, that is exactly what I asked about.
This is also where you've lost me.

Your answer doesn't explain how/where/when it's converted.
His answer doesn't explain how/where/when it's converted.

I didn't read the link he provided at first since it appeared to:
  1) be provided in reference to psp_selector
  2) not be related in any way whatsoever to conversion of env_selector
  3) appeared to only be about the switch to protected mode
  4) not be related to any issue other than initial CS, DS selector setup

His provided link does explain where environment selector is converted.

That answer is that it's created in the initial DPMI entry point call.

So, that has now answered exactly *HALF* the asked question ...

I'm not sure whether to thank him for that or not since he didn't bother
to explain why I needed to reread that.  I'm sorry that I overlooked that
or ignored it multiple times.  Of course, that would explain why I asked
and why the link appeared to be of no use whatsoever to me.

I'm not going to ask you two for the other *HALF* of the question.
I suspect that doing so would do irreparable damage to my psyche.
If someone else wants to reply, thank you for that.  Otherwise:

Later,
