is there a delta between media_entity_remote_image and media_entity_image

Not sure what you mean. When I visit https://www.drupal.org/project/media_entity_image → , I see a different project as expected. Happy to look again if you can give more info.

Just trying to remember.

This module is called "Media Remote Image"

But has a path called media_entity_remote_image e.g.

https://www.drupal.org/project/media_entity_remote_image →

However there is another module called Media Remote Image (oembed) that has this name:

https://www.drupal.org/project/media_remote_image →

Yeah so I was probably just getting confused.
