From a repair job in San Bernardino This is an example of the garage door opener position in relation to the garage door top section clearance. Not all doors are installed the same way (correctly).

The main problem with garage doors and openers being installed out of the manufactures specifications, is that can cause stress on parts and lead to excessive wear and eventual breakage.

Another factor is that the opener has trouble sensing obstructions if the top section of the garage door is to far away from the opener rail and then bad things happen to the top section I.e the top section get pushed down to the floor instead of forward to the header to close the top of the door.

    Those brackets are not installed wrong. If you rotate them so the roller tube is higher on the panel, it would need to be extended out further because it is placing the roller further into the curved track. The arch of the top panel would remain virtually the same. This is typical of all sectional overhead doors, without the use of low headroom devices. The installation of your operator appears to be fine.

    Marantec openers are no the greatest out there... I'll give them that they can make a very very quiet DC motor. But come on... Chamberlain LiftMaster. May I say more?
