On some rare images (ones with blue sky gradients come to mind), you may need to increase the ETC1S `-comp_level` setting, which ranges from 1 to 6. This controls the amount of overall effort the encoder uses to optimize the ETC1S codebooks and the compressed data stream. Higher comp_level's are *significantly* slower.
