My personal ReShade preset for Baldur's Gate 3 (w/ HDR). Unlike most presets which aim to substantially change the look of the game, mine is quite subtle, adding a little depth and sharpening, and a little extra bloom, especially in really bright scenes. The SDR screenshots don't do it enough credit: it looks better in HDR where there's room for that brightness to, well, shine.

Here are some 4K comparisons:
