It's not at all subjective. On 103, and 104, the HDR colors look like the second and third screenshots no matter the color temp. On 105, and only on 6500K, do they look purple. All the same settings otherwise. So there is something off about HDR impl...
Yep, I have the same symptoms. 105 with purple tint. 104 doesn't, but it has some strange color banding, but that's not the focus of this discussion. I'm currently using 103.
I use MCM103, it looks okay. I use MCM105, it looks exactly like Joshy25's state, on all the games he noted, as well as youtube test videos. It's not just a matter of calibration. Something is off. You don't need to be dismissive.
