Short description of error
When rendering project night rendering with cpu+gpu, the gpu renders brighter than cpu. Also, rendering results between gpu and cpu standalone give different results as well. gpu is brighter. Probably user error. If this is too much to look at, I understand.
Exact steps for others to reproduce the error
Open attached file and render. Scene is set up to go. Sorry, not simple file. Because I do not know what is the issue. The anomaly is most noticeable on the image on the right hand side of the rendering.
Attached are some images that show what is happening on my end. Plus a finished GPU only rendered result.

1 GB files are not practical to investigate.
Please try to simplify the file.
@brecht, is this a known issue?
Seems to be the same problem as #70501 (Cycles GPU rendering produces a different result than CPU) so I will merge these reports.
Closed as duplicate of #70501
