Question Camera output texture looks washed out in Quest build but fine in editor

So I've used a second camera that outputs to a texture which a URP unlit material uses as the base map texture for a scope. Everything works fine within the editor but when built, the image looks very washed out, I can sort of improve it by changing the base map colour to something a little darker, but it's still somewhat washed out and it shouldn't be the case given it's working fine within Unity (2019.3.5f1). Any tips on how to overcome this would be appreciated, thanks in advance.
