I find f.lux unusable for quite a few TV shows on Netflix on my Macbook. I don&#x27;t have an issue with the colours, but it introduces artefacts in very bright areas which are really annoying. Sure I probably shouldn&#x27;t watch Netflix before bed, and I don&#x27;t when I need to be up early etc., and I probably could fiddle with settings to fix it - but it is noticeable and annoying.
