Okay so... by the image it looks like a separation between the actual display and the outer most plastic. This is likely either A: A design flaw or B: A bad product that needs an RMA and replaced or returned. I would not doubt it being a design flaw which would therefore then mean you would have to wait next year for the new generation of foldable phones for this to potentially be fixed.

NOTE: This is by far professional opinion since I never worked on a foldable screen, but this is what my assumption is just by looking at that single image.

I can not say in the most professional manner how something like this has happened (I never made a foldable screen for Motorola) but I can only assume its because of premature technology (In other words... "New Technology" which therefore can and usually always will have issues) or a design flaw that was overlooked (Which is pretty common sadly).
