Problem: Some exports with 8-bit palette may result in a 4-bit image.

Description

When exporting a map from ArcMap and choosing the 8-bit paletted, 256 color option, the resultant export only contains a 4-bit, 16-color color map.

Cause

If there are less than 16 color values in the map, the resultant export contains 16 color values to minimize file size.

Solution or Workaround

This is a known and expected behavior.
