Issue description

The Exposure multiplier in the tonemapper affects environment brightness drastically.
The effect is visible with or without a reflection probe, and creates inconsistencies between baked GI and the world's reflections with the latter being too bright in comparison.
Reflection probes need to update to be affected.
Specific to the compatibility renderer, does not occur in forward+. Haven't tested mobile.
Could be related to #102643

Exposure 1:

Exposure 5:

Exposure 5, reflection probe refreshed:

Steps to reproduce

• Load MRP
• Update reflection probe at exposure 1
