This video shows how the default dynamic range of Blender (the f-stops to a photographer) impacts renders and the massive impact to the look of rendered graphics in Blender.
Here is Blender Gurus default, filmic and reference photo images.
So what is the f-stop or dynamic range of Unity and does it impact the look of our games?
Depends. If you’re using the old default gamma color space, is the same as default Blender. Both Unity and Blender would be rendering using sRGB. That’s why step 1 of realistic rendering is changing to linear color space. Step 2 is use a tone mapper / color grader, like the one in Unity’s post processing stack which I think defaults to use ACES.
