Dell Premium 16, 4K OLED screen calibration issues

Hello,

I bought this nice Dell Premium 16, with the OLED 4k screen. I am a professional photographer and need to calibrate the screen.

I had an old Spyder5 but this produced very bad results, i think because of the OLED screen. So i went on and purchased a Datacolor Spyder (2024). This produces better results but still looking at the screen i think its a bit off (i would say too cool but not sure what is really wrong with it).

I have only the Intel Graphics software on my machine and have removed the Dell Optimizer..

So how can i be sure that i have properly calibrated this laptop so i can get the most of it?

Thanks!
