Q27G3XMN + HDR + CRT Shader

[LB2UI]

I am trying to get a good crt quality feeling when playing SOTN for PS1 in retroarch.
I have adjusted crt shader settings and have ended up with this.

I have done color and mask settings but still experimenting before i enable subframe shader in retroarch and then select crt beam simulator shader.

Anyone know of any good settings for 27 1440p HDR screen for emulating CRT?

Weird behaviour when display framebuffer (when the setting low input lag is turned off) is turned on.
When display framebuffer is off then it works great, even in HDR mode.

I wonder if anyone know how i can color/contrast calibrate for a specific crt monitor type or standard.
