No, it's not. (And I say that as someone who likes ST: D a lot and also like The Orville) ; but that said the Star Trek format itself is no longer original and hasn't been for decades - and even though ST: D is a serialized story more about war and ultimate personal redemption <--- That's not a new plot element, even for Star Trek, so it definitely going to have some of the usual tropes that come with this type of story.
ST: D isn't trying to be original here (hell basing it as heavily as they did into the TOS era and tying it to established TOS characters proves that); they're attempting to be innovative with regard to the overall tried and true 'Star trek' format and see if overall the existing fans will accept it, and with such innovation hope to add new Star Trek fans to the fold.
How successful they'll be is anyone's guess atm; but it appears CBS (and CBSAA) are pleased with the results to date.
As for The Orville it's trying to ape Star Trek (all 50+ years) as much as it can. It was never conceived as a wholly original concept; it was conceived/designed as derivative from the start with the hopes it would bring in people who enjoy that particular formula.
