It's probably an easy win for them. It also might have been a good target when they were ideating on specs. Having these pro certifications gives the devices a halo of premium quality.
This also keeps their development targets at the state of the art.
Regular consumers probably don't buy these displays in bulk, when you can get very nice displays for less than half the price that are 98% the same on specs.
So targeting checkbox-compliance for places like hospital systems is probably an easy win to generating / keeping some long term contracts.
