I am on 2021.1.2-R2.
When I render out to PNG 8bit per channel, the output is very overexposed compared to the LV. It's like the gamma has changed to 1.0 instead of 2.2.
Sometimes this doesn't happen if I start rendering from frame 0, but if I start rendering from a later frame the output will have different gamma. I don't have camera imager turned on either.
Here are my settings.

How it looks.
