Short description of error

Exact steps for others to reproduce the error
Hello guys! Im facing a wierd color when Im trying to migrate my old project from 4.1 to 4.2. I noticed there are some color brightness difference between these two version. Please see the comparison below

I really want Blender 4.2 can have a much closer and similar color display to the 4.1 version!
So, my ultimate question is, To achieve the same results in Blender 4.2 as in Blender 4.1, which settings need to be adjusted?

First demo file is just for demostration only

File name: Color Compare.blend
Color Compare.blend

This is just a simple cube setup with a custom HDRi from poly haven. As you can see there is huge color difference, every settings are remain the same.

Second demo file is from old project, simplified edition, sorry about its size since I have to attach a 4k HDRI inside so you can clearly see the color difference.

File name: GrassLand-ColorCompare.blend

As you can see from the image above, in 4.2 object brightness from the world seems way darker than it was in Blender 4.1. It is extremely wierd and I dont know where I did wrong in my project.
I tried to follow the Official Blender Migration setting from

EEVEE migration from older versions to Blender 4.2 LTS

I still cannot find where the issue is.
Could anyone willing a help a brother out? Is there any setting i was missing to cause this issue?

Thank you so much in advance!!!

Best regards

Hi, thanks for the report.
Re cube scene: I don't see any difference apart from the bloom in 4.1. In 4.2, EEVEE results are actually matching with cycles.
Re GrassLand-ColorCompare.blend: adjusting sun threshold (at word properties > Settings) resolves this.

Not sure if this is a bug, forwarding to EEVEE devs.

Thank you Pratik for the fast reply! Yeah on the second project GrassLand-ColorCompare.blend , adjusting the sun threshold indeed works!
FYI for the first demo file Color Compare.blend I tried adjusting the same threshold but no significant change. From my monitor you can clearly see there is subtle color change between these two cube show below

Is that mean, Blender 4.2 new eevee next has completely rewrite its core so no matter what i try, I cannot get the same exact result as before. Is that a yes or no? If that is the case I can finally rest in peace so I would bother trying to tinker more setting trying to fix it, and happily accept its a fact haha.

Thank you
