Material to override emissive colors

So this has been a common question of mine. I’ve made a basic outline material, however it draws over any emission I have so if there is a glow and an outline conflicting with each other it looks pretty ugly. There’s the source of the emission, an outline overwriting it completely, then I want to detect if the pixel I am working has any emission applied to it, so I am able to say “Ok, just leave this pixel be, don’t draw the outline over it”. I’ve looked through the scenetexture node, and found nothing.

The shuriken isn’t really important since I can just exclude it from the custom depth, just an extreme example. The cylinder is the prime example, as I just want the non-emissive portion to be outlined while the emissive section overwrites the outline. Thanks.
