If you know that this is not possible at the moment, I think it would be better if you change the topic to more of a suggestion to the Figma team and change the category to #product-ideas. This way people will be able to vote for your suggestion if they have the same issue so Figma team will see it and hopefully improve this behavior in the future.
Yes, this is definitely a bug. I’ve looked into it myself and I have to say that they got it wrong. sRGB/unmanaged are swapped on Windows. Color management is generally a very complex subject and modern IT software companies don’t have the know-how to set it up correctly. It’s not just a problem with Figma, but with all trendy modern tools. Interesting that it doesn’t work for you at all. How does it work for you today in the latest versions?
