I had the idea to render a similar scene showing the effect of varying the rgb
components of the irid_wavelength global setting.

https://wiki.povray.org/content/Reference:Global_Settings#Irid_Wavelength

Even though "You may have multiple global_settings statements in a scene."

Apparently, "Whatever values were specified in the last global_settings
statement override any previous settings." and this affects all the irid{}
statements, you can't sequentially assign different global settings to objects
in the same scene.

Kinda obvious, but I did it just to check.  Bummer.

I'm voting for irid_wavelength to be moved into the irid {} code of the finish
{} block in future versions.
