Super bright emission not so bright on iOS

Hi

I have a transaprent standard material with a very bright material behind it (emission on 50 multiplier).
In the editor this shows up as white through the transparent material
in my iOS build, it is very dimmed.

I have all graphic and quality settings on highest and HDR is on. What could be the problem?

Is it dimmed only when viewing through the transparent material, or is it dimmed always - on iOS, even when not viewing through the transparent material?
