True Tone on external display mismatching

Hi, I have a Macbook Pro 16'' 2019.

The true tone has always been working fine even on the external monitor, but it's been a while since whenever I have true tone on the external screens appears with colder and blue colors, mismatching the setting of the Macbook screen, while it gets the same color balance if I turn it off or if I turn on the night shift.

I've tried to reset the PRAM but didn't change anything.

I believe this issue appeared when I went on with the OS from Catalina.

Do you have any advice on how to solve this? Thank you
