Diffraction in reflectance is caused by IOR. Not sure the effect is visible without caustic (caustic should be set much higher than the default 1000).
see this article https://www.chaosgroup.com/blog/understanding-glossy-fresnel (different software, but the physic principles are there)
You can try to set different value in IOR, set fresnel effet to 100% and see if it changes something.
Would adding blurry reflections get you the effect you're looking for?
