I'd suggest lowering the Saturation in tone mapping (you can up the saturation in the volumetrics themselves to compensate if you wanted to preserve the strong green blue color in the glass), also enabling Sharpen and Blur and Denoising will help with the noisy look (not with the color intensities though :) ). I did end up messing around with the abbe number too just because I liked this look, but even with the original abbe it avoids the superbright colors in the rainbow area. Only ran it for 25 passes or so. I stripped the tone mapping stack down to just the minimum, LUTs and curves and Advanced Filmic could be used to further tweak.

Oh yes! I always forget about post-effects in my experiments. This might be a problem, thanks for your time!

Thank you for your answers, guys!
But I'm specifically trying to get a stained-glass effect. With a dispersion value close to "1". Something like that in the picture "ref".
But even with values ​​of 30-50, such artifacts appear in reflections. There is a feeling that the dispersion is multiplied. But only in some selective reflections.

Below is the variant "without" the problematic reflecting object. And one more option with a "minimum" dispersion parameter, and still there is a problem in reflection.

Hi there, how many passes have elapsed for this image?

This thing appears around 6-7 pass. And does not change throughout the render, up to 100-200 passes.
