when switching to the Denoise pass any shadows on a Shadow Catcher material become much lighter

is there a way around this?

I think I recall Ahmet saying that the Shadow Catcher object is sill there mostly for backward compatibility, and can be buggy with more recent features. AOVs are really the intended workflow for shadow isolation. Abstrax posted about it a few months ago. And don't forget that the Shadow pass only holds direct lighting shadow info. For full shadow info, you also need the indirect diffuse pass to get the subtlety.
