The image isn't captured as displayed in HA, and is captured in grayscale even though I specified "TrueColor".

I think that's just what your dashboard looks like when rendered at 160x128, try a larger screen size for debugging purposes

Yes, the rendering screen height/width are working just like your desktop browser would if you resize it to these dimensions. Which probably also would result in the same visualization.

Try increasing the width+height. Maybe you can work with the scaling options to achieve whatever you're trying to achieve? :)
