Likely it will. Intermittents are the hardest to troubleshoot.
Be careful what you load and update.
I have exactly the same issue. I was typing on whatsapp when suddenly screen get black. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
I already flashed fresh stock Android R rom and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking). I'm draining battery now with some apps that also vibrate phone. Display is still dead.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Were tou opening and closing the camera while mirroring screen? or on blind?
It seems in your case, the display went back to normal as strange as it turned off.
Could you please share the mentioned youtube video?
Hope I have that lucky as well.
