I don’t even know what you mean about Outlook and Teams, are you saying the text gamma is wrong? Or they display images wrong?
> Developers assuming that RGB is a triplet of 8-bit numbers and that maths can be naively done to those numbers is one of my favourite examples of the Dunning Kruger effect. [1]
RGB is a triplet of numbers, and you can do naive math on them, to convert to another color space for example. RGB in fact is a naive color space in the first place, not well defined, and does not have a defined gamma, so all math on RGB is de facto naive. sRGB is not RGB.
BTW, please don’t invoke Dunning Kruger snidely to suggest someone’s wrong. It’s a bad meme because DK is widely misunderstood, and suggesting someone’s an example because they’re wrong, ironically, perpetuates the misunderstanding. People making assumptions, or doing something wrong, or even being incompetent, are not examples of Dunning Kruger. People being over-confident is also not an example of Dunning Kruger: they showed in the paper that there is a positive correlation between confidence and competence for the tasks they measure. Therefore, you cannot know when something is an example of DK or not. The paper has rather poor methodology, it is full of priming and leading questions, including the title, and it went viral not because it’s right but because people love to believe the mistaken idea that someone who’s very confident might be incompetent, even though that’s not what the paper demonstrated. Also the Dunning Kruger effect probably doesn’t even exist, plus replication attempts have shown the opposite effects for more difficult tasks, like, say, engineering.
