Get a hint that this notification's {@link BigPictureStyle} (if present) should be
converted to low-bit and displayed in ambient mode, especially useful for barcodes and
qr codes, as well as other simple black-and-white tickets.

@return {@code true} if it should be displayed in ambient, false otherwise
otherwise. The default value is {@code false} if this was never set.
