How to increase range of "color bleed" of Lumen?

Per the docs:

Lumen Global Illumination solves diffuse indirect lighting. For example, light bouncing diffusely off a surface picks up the color of that surface and reflects the colored light onto other nearby surfaces — creating an effect called color bleed.

In the attached video of my scene, the red light coming from rays bouncing off the lampshade disappears at a certain distance. How do I increase this distance?

Changing the Lumen Scene View Distance and Max Trace Distance has no effect. That kinda makes sense, since diffuse lighting in general isn’t disappearing at this distance; only the contribution to the light’s color from the lampshade disappears.

Changed every option I could find. Ideas?
