Honestly, Destiny 2 doesn't look like a massive leap up from D1, so I doubt it's pushing the GPU of the original PS4s to the point where HDR would be an issue (not that I'm an expert). So I'll say "maybe", but yeah, there might be stuff neither of us knows holding that back.

While Destiny 2 might not look like a graphical improvement when compared to Destiny 1, it would be wholly incorrect (as you seem to be aware) to presume that, there for, nothing has been done. To what has been publicly mentioned, it is safe to say that they are using the extra horses less for looks, and more for game-play related items. Scope and size of the maps, number of foes, so forth.

The question then becomes can the hardware support all the game-play upgrades plus the newer visual hardware niceties such as 10 bit color, HDR, 4k, and so on.
