Blender Viewport Shading in Unity

I modeled a little low poly forge with Blender 2.83 and used a color palette to colorize my faces as described in this video. Everything looks nice and fine in my Blender view:

But when I export the model as FBX and import in unity, the colors are completely different:

I had my settings for Blender Viewport Shading like described in the video linked above. My question is, is it possible to emulate or change the unity settings so that it looks just like in blender (or something like that)?

The difference is just to big and I already tried all possible combinations on the model import settings and material settings in unity.

Anything new on this end?

Bump, same issue
