The core tech is what it is and there isn't much they can do to "improve" it.
Where the changes have come in the panels is in how they use the display film; different substrates, backplanes, lighting modules, sealing...

The biggest gain and hardest thing to implement is the plastic substrate. At some point they'll figure out how to do it affordably but it's one of the grails of tech and nobody has really, ahem, cracked the problem.

That they managed mobius is impressive enough.
