Hmm you're either confusing terms or you're inadvertently applying cfw to the sysnand.
Sysmmc and stock are the same thing.
Using ("most" ) sysmodules and installing nsp/xci titles on sysmmc may flag your console for a ban.
You should use cfw on Emummc instead. Unless you know what you're doing or don't care about getting banned.
To answer your question, I don't think Nintendo has a way to monitor the contents of a screenshot, so taking screenshots of overlays and cfw elements should be safe.
But it doesn't make sense when you say "taking a screenshot on Sysmmc and then going back to stock" because, again, both are the same thing. If you're applying cfw to Sysmmc, chances
