:sbadau, if you think that's a regression, could you try to find a regression range using for example mozregression?

Since the on-screen brand name is still visible, marking this as access-s4.

While adapting images are not required for HCM, we probably still want all users to be able to see the logo for all good reasons, thus we could modify the image SVG to include system colors that would be visible in HCM too - there are few examples in the HCM SVG playground, NDA'ed link)
