S3220DGF EDID issue, EDID values for HDR are wrong. How 2 fix?

I have one of the first models of the Dell S3220DGF, a monitor that I love. However, my EDID values are totally wrong! I mean, the max luminance and the min luminance are the same, and average max luminance is set in the EDID to a value even less than a 80 nits LCD.

This causes issues with HDR captures, they look washed out, so do some apps like SpecialK and others. 

These are my monitor's EDID values.

These are the correct values, this is from a friend of mine, to whom I recommended this monitor and he purchased it some time ago. Everything is fine here:

In mine min-luminance is the same value as max luminance, average is like min. That cause all kinds of issues.

How can I correct the EDID values of my monitor?
