Is There Any Scale Where The Distribution Of Electric Charge Within A Neutron Is Relevant?

A neutron contains valence quarks with both positive and negative charges so tightly bound that on most if not all conventional scales the baryon as a whole can be treated as a single electrically neutral particle.

My simplified layman’s understanding is that the strong force typically dominates the electromagnetic force on scales for which it’s relevant at all, but is there any scale where the electromagnetic force operating on the charged components of a neutron is relevant to understanding the behavior of those components or the neutron as a whole?

Is this expected to change at sufficiently high energy states (e.g before discrete atomic nuclei formed)?

The charge distribution asymmetry of a neutron would manifest itself as an electric dipole moment, but so far there has been no nonzero measurement of the neutron electric dipole moment. So, it's safe to say that it's pretty irrelevant. If we could detect it, it might indicate "beyond standard" physics, because the standard model prediction for it is so tiny.

The magnetic dipole moment, however, is non-negligible, to the point that neutron beams can be controlled with magnetic fields. Neutron scattering is an extremely useful tool for learning the magnetic properties of materials, because they bypass those pesky electrical properties.
