Blue Shadows on Lighting Quality High (PC)

Whether this is a bug, or a unfinished graphics feature would be interesting to know.
The graphics settings options are weird, on ultra preset you can't really get the shadows to be blue. but on low preset you can get the shadows to be blue by setting Lighting Quality to High (this also deletes the clouds for some reason - this is a different bug I dont care about).
When switching to the Ultra preset from the altered Low preset with the shadows blue, sometimes the shadows will be blue as well on Ultra - but it's inconsistent. The effects of it are nice actually, I think it makes the game more vibrant.

Another example, although this one was done in the low preset with graphics manually turned to Ultra

The biggest difference Is when you're in the shadows of buildings it has a colder vibe, I personally prefer this aesthetic, it looks more realistic - but opinions might vary, I think it's an overall improvement because it balances out the yellow light - making it feel less like a brown filter on the game. It makes things seem more colorful.

But given how out of the way it is to get the shadows to be blue- especially on ultra, I dont know if it was intended to be in the game, I personally hope it does get put in fully though - skating in the shade always felt off in skate.

Devs released a video showing off darkslides and they don't have blue shadows, It looks like they are playing on Ultra.

I made a video that might describe things more clearly maybe:
