Does that mean it shows as blocked on expertflyer?
Looking at KTM-DOH I see those seats as blocked and similarly on CMN flight which I took with the new seat. So I presume that is the correct way to see it on EF?
No, the seats will simply not be there in a new config airplane. If they're blocked, then they have the current config loaded but QR (rightfully) doesn't want to assign them in advance to avoid customer care issues in case the new configuration is substituted into the flight.
