the lsit onlyshows 2019 model is.
 
I am perfectly happy with the LG 24" Ultrafine that I bought a few days ago to go with my 2018 15" MBP..... Lovely monitor, is working just great, no fuss, no muss.....

Only Macs with DisplayPort 1.4 are supported? Dual DisplayPort 1.4 is required for 6K. DisplayPort 1.4 is also required for HDR.

But it seems that the display has a 5K timing mode that could be supported by DisplayPort 1.2 Macs, according to the info in the mtdd files in the /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-610 folder.

DisplayProductID-ae21
DisplayProductID-ae22
DisplayProductID-ae23
DisplayProductID-ae2d
DisplayProductID-ae2e
DisplayProductID-ae2f

I'm not sure why there's 6 files for the XDR. Does it have different modes that you can select? Or different modes depending on how the display is connected?

I guess we'll need someone to try. I would like to get a real EDID from the display instead of just the EDID from the mtdd file. The following command will get the info. Indicate in the output file name how the display is connected.
Code: 
/System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -a > AGDCDiagnose_a.txt 2>&1

Why isn’t the 2019 MacBook Pro listed?

I bet the old Vega 16/20, along with the 5300M/5500M is robust enough to push the display but can the older 555X/560X handle it.... ON TOP of doing graphically intense loads?

If the XDR is going to rob more than half of the GPU’s performance... what’s the point

I’m even skeptical about my 5500M with its measly 4GB

The 2018 or later 15" supports the Pro Display. The compatibility document was updated later.
