Graphics quality / standard shader in webGL

Unity Engine
1

I have textures set to Crunched
Quality settings to fantastic

However compared to the Editor the webGL content looks very washed out.

in webGL:

in Editor:
2275899--152692--editor.PNG

Is there something I’m doing wrong? Is it this issue?
Anyone know of a workaround?

Thanks!

Tried building with vertex compression set to ‘nothing’ and ‘Optimise mesh’ to false. Neither made a difference. Can’t find any documentation on these options either (5.1.3p1)
