So I actually listened to the entire podcast while driving back home tonight. He knows his stuff, but as much as he talks about the importance of calibration, as he should, he doesn't mention the fact that you can't calibrate the XDR. He seems most impressed with its contrast ratio compared to his Eizo, but he's overlooking color accuracy, which is quite strange. He talks about CalMAN and calibrating his LG OLED, and you can (and should) do the same 3D LUT calibration on the Eizos (I prefer LightSpace/ColourSpace myself over CalMAN, but same principle). You can't do any of that on the XDR. I don't see where the XDR would even fit in his workflow TBH. You have your main monitor, your waveform, and the larger monitor with a direct SDI/HDMI feed. If I was purely a colorist, using Resolve, I would have an Eizo as the main monitor calibrated with 3D LUT, a cheaper LCD for waveform, and a 48" LG CX OLED calibrated with 3D LUT. Unfortunately, the XDR falls short in this very important area. I know Apple has hinted of "upcoming" calibration abilities, but seems tied macOS/software, no idea really TBH.
Read some comments from other pro colorists, and you'll see why the Eizo is preferred by them over the XDR.
EDIT:
I just looked him up, and here's his workspace. He's using the XDR has his main working/editing monitor and the Eizo for his color critical work
LG up high for OLED/client check, scopes, waveforms, etc.
