I have to wonder if “embed ICC profile - even when it’s sRGB” belongs in the Feature Requests section.
I haven’t run across this issue (Windows / IrfanView as viewer). Looking at my Irfan Settings / Color management, I have "enable color management set to display using my current monitor profile and "apply also for images without embedded color profile (slow!), set input ICC to [sRGB] - which probably explains why I don’t see an issue.
I just checked Feature Requests - there is a request to embed sRGB. I voted for it - maybe we all should?
