Yes, all of these displays currently have "Monitor Software Version":
3.01, 1.11, 5234, 3.00, 0.1.d
One wonders what all these numbers stand for?
3.01
1.11
5234
3.00
0.1d
Presumably they are for different components
firmware within the display?:
panel / camera / speakers / USB ports / TB3 cable.

One unrelated good thing I only just noticed...
If I have windows spread across my two 5K screens, then unplug the two 5K's (so only using the MBP screen), obviously all the windows then appear on my MBP screen.
But, when I replug the two screens back into the MBP, all these windows usually go back to exactly the position they were in on the external screens, which is super useful, as you don't have to reposition them again.
Perhaps this is something that has been around a while, and I haven't noticed it, but anyway, this is a really useful function.
