The attached file should show the problem.
I made an EXR file to represent a star field, just faint stars of varying luminosities and colours.
I set it as the background for my renders using planar projection.
Things look great in perspective views but no stars are visible in: top, bottom, left, right views.
I’m rendering using cycles.
I imagine that I should be able to see the stars in all views so I think that this is a bug.
The file has a completely transparent EXR with no stars in them? Both Rhino and Blender show nothing but transparency
Anyway, environments in parallel view won’t work as in perspective view. Instead I suggest rendering your model with say transparent bg and then combining render with backplate separately.
That is so weird because I see the stars here: https://viewer.openhdr.org
This is the exr file itself.

I just dragged it onto the file upload area on the page and there it was.
And I see it in my renders but files uploaded here don’t fare well being converted from png to jpeg so I didn’t bother uploading them.
But, yeh, I can do the transparent background hack but I was born lazy
