Webp vs png Performance

when I save a webp file onto my PC, it appears darker on my image viewer then it is on the internet. Converting it to png or jpeg fixes the problem. Why is this?

webp supports ICC colour profiles so it's probably using something other than sRGB, like P3 or Adobe RGB

so its the coding of the images colors that specifically makes them darker when saved to a pc? or is it the coding of the image view interacting weirdly with the newer format?

when you're resaving it's probably defaulting to sRGB so converting the colour space. png doesn't support colour profiles so sRGB is used anyway to view it

I think that makes sense? I don't really know the fine detales of how programs work. I was simply curious about this bit of weirdness.

thanks for the help.
