It would be awesome if you could add other problems using the same format, so that we can find them easily.
Screen: Shadow around the edges
Around all of the edges drop shadows are visible. They are giving the impression, that the screen and the bezel is separated by some distance. This is not the case, as you can see by looking at the screen from the side. The shadows are therefore no real shadows but areas with limited brightness. This limited brightness probably results from the fact that there are no more LED under the edge. The Pro Display XDR is apparently having the same problem.
Are mitigations possible?
Apple might try to increase the brightness of the outermost LED. Maybe they are already doing this, maybe not. If they are already doing this. things will not be getting better with software updates.
Screen: Blooming
Bright elements on a black screen are surrounded by an aura more or less visible to your eyes. This is called blooming and results from the total blackness of the screen due to switched of LED.
Are mitigations possible?
No mitigations are possible, if you want all the other LED to be off and the rest of the screen to be black. The light has to come from some of the LED and the corresponding LED zone will be visible as "blooming". Apple could decide to change the algorithm and not to switch off the other LED but then your contrast will be bad and the screen will look like a non XDR screen.
Thunderbolt 4: Speed issues
Apparently (at least in my test with a 10 GbE adapter) the TB4 connection does not run with full speed. A probable explanation might be power limitations as high speed devices like NVMe and 10 Gigabit Ethernet adapters draw a lot of energy from the iPad which of course as a battery powered device does have its limitations. There might also be software issues, as iOS-input/output-routines might not be optimized for Thunderbolt yet.
Are mitigations possible?
Apple might improve the software responsible for I/O and you can provide more power to the devices by using a Thunderbolt dock.
