Overexposed rendering in LWRP on iOS

I’m posting a video to demonstrate the issue. The big hexagonal towers are 300 units across, the shadow distance in LWRP settings is 2000 units.
Does anyone have any idea what is causing this?

 

I've upgraded to 2019.1.5 but still had the issue.
I then added the following line to my link file:

Code (CSharp):

1. <assembly fullname="Unity.Render-pipelines.Lightweight" preserve="all" />

Still no improvement.

I'm attaching the LWRP asset settings below

 

A few more screens

I've tried the LWRP>LIT Light shader:



I've also tried using a material from the LWRP example project:
In ios:



and in the editor:



Mark that this doesn't have the 'sphere' distance issue, the overexposure happens at every distance.

Another thing is that I see the sphere effect (but differently) in the LWRP example project. This when enlarging the room 100 times. I'll post an image later...
