Looks Genuine to me as far as what I can see the colour on the sticks look great to.
I recently purchased a box of medio siglo cohiba looked great smelt and tasted fairly average, couple months later (3 months) was a great smoke.
Some times you just get average batch happens even at lcdh stores, unlucky I guess let them rest for a few months and then try again.
Also take into consideration have you been smoking other great sticks limitadas or something higher end and then going back to robustos can be a bit bland.
