Big discrepancy between Android and PC rendering! How do I fix?

Hey all.

I just finished my Mobile game, and after some discovery, I learned that porting a PC mode wont be too difficult in terms of changing game mechanics and key bindings. The issue is that the visuals look much, much darker when not rendering in ‘android ES2’:

I was wondering if there way a way to force the emulated ‘android es2’ rendering so I can get the game to look similar to how it looks on android, because if not, I believe my only way to fix this is fork the project and redo all the lighting in the entire game from scratch, and that would take too much time for something that would otherwise only take a few weeks to port.

Is there any way to do this? Or something else that could fix the darkness problem? I tried fixing it with a post process volume but all it did was wash out the frame.

Thanks in advance,
