camera projection ray-traced vs classic 3D

I've projected a photo on a white solid. Converting the photo and the solid to a 3D-layer and using a point-light to cast the photo on the solid. The photo only casts shadows and transmits 100% of the light and the white solid accepts shadows.

This scene works in the basic-3D world, it also works with ray-traced set to quality 1/draft. But it gets blurred with a setting above 1.

It seems that the photo at scale 1% and at a distance of 10 pixels from the light acts different, than a photo scale 10% at a distance of 100 pixels from the light. The latter one gets less blurred by the ray-traced setting.

So my question is, what causes the difference?

(P.S. Does the point-light get in ray-tracing a cubic dimension?, instead of a infinite small point without a surface)
