The biggest issue is that monitor doesn't have FALD backlights. Which is pretty much essential to display HDR properly. That aside, that is a very nice monitor.
You concerns over 8bit VS 10bit are misplaced. Very few displays are true 10 bit. The key is that it has a wide gamut that nearly covers the dci-p3 color space. HDR10 will be accurately converted to 8bit by the panel. Yes, there will be some banding due to it not being a true 10 bit panel. But that's not as bad as it sounds.
Also your GeForce 1060 can work fine in HDR10 on this panel. You only lose the variable refresh rate feature by not using a AMD GPU. If you're not too concerned with VRR, then there's no issue with your GeForce card.
If you want absolute perfect HDR on a pc display, you are right to pass. But not for the reasons you posted. The only real problem with HDR on this display is the lack of FALD.
