The ImageBuffer constructor creates a SkDevice for a non-accelerated canvas first. Then, if an accelerated buffer is requested it will try to create an accelerated SkDevice, if successful overwriting the non-accelerated device.

This can be optimized to first try, if requested, to create an accelerated SkDevice and only create the non-accelerated device if that fails.
