External monitor do not follow day/night colors/brighest

Sorry, I wrote about Plasma6, but I do not known if this is bug or I mess up with settings. I will search bugtracker, if somebody told me, this case should not happen.

So: My builtin screen are darker due to day/night scheme, but external is not.

I discovered it was made by enable HDR option. Once disable it, day/night was working again.

Please do submit that as a bug report!
