Is this how Kerdi is supposed to look after water test

My contractor installed Kerdi membrane system and we waited 48hrs to water test. We filled and waited 24hrs. Water level stayed right at the line. FYI he has used Kerdi before. We were both surprised and worried to see water moisture had wicked up above the corner band. See pic. Is this normal? Arrow points to water level that stayed solid for 24 hrs but it’s clear there is moisture above water level. Thanks for feedback.

It's probably ok and I know in Kerdi video they install the pan last but I think like a water drop and so I install the pan first then the corners and then finally the walls so even if a drop got through it would run into Kerdi material. Just MHO.
