Steps to reproduce:

In HDRP:

• Open the Provided package
• Drag and Drop the VFXG_BugRepro_DecalEmissive_HDRP vfx in a scene and put it close to a ground plane object.
• Open the VFX.

In URP:

• Open the Provided package
• Drag and Drop the VFXG_BugRepro_DecalEmissive_URP vfx in a scene and put it close to a ground plane object.
• Open the VFX.

Actual results: 

While they all have the same color value that goes above one, only some of the present decals are glowing.

If you take a look at the decal output, you'll notice that they all have the Color Mode set to Everything (Color & Emissive). This should mean that setting a value higher than 1 in a Set color should make them glow (with the proper/default post-process settings).

Only the second and Third Decal outputs are glowing.

The second is glowing, as a workaround has been used:

The Third one in HDRP is glowing thanks to the option Use Emissive Map.

Expected results: 

With the Color Mode set to Everything, the decal should get emissive and bloom if the value goes above 1 without needing a workaround or checking the Use Emissive map.

Notes:
The Use Emissive Map isn't present in the URP Decal Output without wokaround.
