If anything, Discovery seasons end a lot more hopefully than the average DS9 season. Every Discovery season has a happy end, in the finale of DS9's season 2 we learn that there's a powerful enemy waiting for the Federation, season 3 ends with the revelation that changelings have infiltrated everything, at the end of season 4 our heroes suspect that the Klingon Empire is controlled by the changelings, season 5 ends with the start of the Dominion War, season 6 ends with the death of Dax and Sisko feels abandoned by the Prophets and takes a prolonged leave of absence.That's pretty much what happens at the end of every season of Discovery.
I'm pretty sure each of these DS9 season finales are more devoid of hope (and better...) than any of Discovery's, but due to the fact that we know how DS9 ultimately ends well (minus the death of a ton of Cardassian civilians...) DSC is perceived as more "depressing" and "grim".
