Personally, I have dark balance set to +4 and I am relatively happy with how things are looking both during day time and night time. Overall things look better, to me.
However, I do think nights can be a bit too dark sometimes at the moment, more so if you want to hunt, but I think the way light is hitting blocks, in general, feels more accurate now, apart from some special cases; like marble and metal blocks.
Marble does seem excessively polished/shiny in the case of lighter tints, but darker tints are more or less what I would expect. I think the biggest issue with marble currently is that bit of the bump map that makes it look like it has a crater on it. It just doesn’t look smooth enough, and to be honest, never really has, it’s just more noticeable now with the shininess.
Metal blocks don’t seem to properly reflect nearby light sources, like the titanium seen in the screenshot below; the diamond tool in my hand does, however…
Personally, I can notice tonal differences between Night Orange and Night Green and other Night colours more easily than I could in the past, and I always have my screen brightness relatively low (40-50 vs the maximum of 100). Before the lighting update it took me longer to tell apart those very dark tints in inventory slots.
Where is your build by the way? I would like to have a look for myself.
