For those running the iPadOS 14 beta on 2017 model iPad Pros I suggest not enabling smart invert at this time. I'm unsure whether this issue is limited to the 2017 models of iPP or all iPads.
I was fiddling around with Accessibility settings this morning on my iPP 12.9 (2017) which had iPadOS 14 Public Beta on it and ended up having to do a restore.
When smart invert is enabled all screen content is black so while the screen is technically on, you see nothing but the glow of the backlit display. I'm guessing that the display and OS are still functioning fine, just nothing can be seen since everything is black. The setting persists with a restart so the only recourse (other than somehow managing to toggle smart invert blindly by knowing where to press) is to factory reset and restore the device from backup if you have it.
Found this thread on Reddit after it was too late and I went searching for information:
