My scene is slightly brighter after transform Unity version, how to fix it?

Sir, Ma'am. I'm a newbie.

Please help this is a serious problem for visual design in my project. This problem happens to all of my scene and this cause a huge amount of cinematic photography problem.

(00.00 - 01.00) Old version.
(01.10 - 02.00) New version.

(Sorry for the voices, I forgot to turn it off)


As you can see in the video. I converted it from 2018.1.9f1 to 2018.3.0f2 and the light in the scene feels a bit different (brighter). What is the factor to cause this problem and how to fix it?

Thank you for your kindness.

 

Sounds similar to this one, perhaps the answers in this post help you further:

Appreciate that sir.

To be honest, those (the link) were a problem for me before and I fixed it already since transform to 2018 (Last year) but this time I feel different.

Those time for me the cause of the problem is they put some setting in and required to be done such as quality setting and light properties.

This time I went to a preference setting and all of the number inside to make sure it is the same, even transform the data folder itself but yeah... it does not work.
