Colors are interpreted too dark?

[franzihei]

For a few days I noticed that even if the sky is bright blue outside the Twitter bot posts really dark colors (e.g. https://twitter.com/colorofberlin/status/1366704559943524353?s=20). Is this expected? When looking at the source video cam files I can only imagine that the color must be derived from the corner of the screens, where the sky appears to be very dark? I would love to see some brighter colors once in a while, I don't think the dark colors are a fair representation of Berlin's spring and summer skies. :)
