Here’s another example of what’s going on in HTML5.
I don’t think it’s connected to the ambient light levels. However, I’m not sure what the cause is. Is it a property of the camera itself? sprite texture? The material? Why does it show more starkly in HTML5 and more washed out in the game engine?
It looks like it’s shading or shadowing, but if so, why is it affecting sprites and tilemaps?
