Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

Monitor testing and Calibration
I wouldn't recommend the DTP94 at this point because it was developed in the days of CRT and standard-gamut LCD monitors with CCFL backlight, e.g. it doesn't have correction tables for white LED which is the most common backlighting technology these days. dispcalGUI can do uniformity... -

nvidia or amd for color accuracy and calibration features
That's a decent test image, I'm using it as well. It probably isn't. That alone won't be enough. The banding you're seeing is a compound effect of all the things I mentioned above. -

Not a good test if you want to look at videoLUT banding, for those reasons: - The Spyder5 software introduces banding by quantizing the calibration values to 8-bit ('vcgt' with entrySize = 1, which means 8-bit), before they get even written to the videoLUT. - Game scenes are a result of... -

Yes, sorry. I implied DVI-D. -

HDMI. DVI will always be limited to 8-bit if I'm not mistaken. -

nvidia or amd for color accuracy and calibration features
Note that a 10-bit monitor does nothing for gaming (unless it has an internal LUT that can be used by calibration software), and you need a Quadro card. -

nvidia or amd for color accuracy and calibration features
Not recently, some years ago (I can confirm for my GTX 465, for example). Most modern AMD/nVidia cards seem to operate like this (assuming 8 bit connection to display): Linear videoLUT: Compositor -> 10-12 bit 1D videoLUT -> 8-bit output Non-linear videoLUT: Compositor -> 10-12 bit 1D... -

Why people don't care about calibration?
Not via the driver, but e.g. ReShade (if it supports the specific game) can be used to apply custom LUTs for full gamut correction, so you're not even limited to whitepoint/grayscale like via the graphics card 1D curves.
