I'm more concerned with the sharper than normal bend, not the aesthetics.
On a new model frame it seems like a design flaw.
yes. more so on the rear with there being slightly more cable drag.Are you concerned about functionality with that bend?

yours is likely a common rookie lbs mistake of cutting the outer housing too long .
the one pictured looks un-fixable and possibly made worse by the direct mount brakes.
I'd say that SB's 'too long' photo is just about perfect and his 'correct' photo is a bit short. Those are single pivot brakes, but adding a cm or so to the length of the housing will absolutely NOT add any friction or slop. No chance. Every team mechanic I know uses what many consider to be much too long of a loop going into the rear derailleur. SRAM wants to see 60-70mm of straight housing doing into the rear derailleur so you end up w/ a loop longer than 40cm many times. Never ever had any problems at all w/ that. Sheldon was probably using unlined brake housing back then. It's more important to have a smooth curve than the shortest piece of housing to reduce 'friction'.
