Swizzling like rabb may yield drastically different error metrics after supercompression
Don't you mean after block compression (i.e. after ETC1S or UASTC encoding? Supercompression is lossless. And therefore isn't this an issue for any block-compressed format? Should we recommend not using swizzle with block-compressed formats?
KTX software currently applies swizzle prior to encoding a ktxTexture2 to BasisLZ/ETC1S or UASTC and removes the swizzle from the texture.
