It's because you aren't protecting the entire line from the shell. You should be moving the single quotes (') to encompase the entire awk expression, not just the {print} part.
Each layer of interpretation removes one level of escape, so direct commandline, strips one \, the awk command strips the next, leaving you looking for a . character.
In the shell script, the first \ is stripped, leaving \\. This is passed to sh, which strips another \, leaving \. Awk then strips the last one off.

ecm-compress
ECM-COMPRESS(1) General Commands Manual ECM-COMPRESS(1)
NAME
ecm-compress - selectively strips error correction codes from CD images
SYNOPSIS
ecm-compress cdimagefile [ecmfile]
DESCRIPTION
ecm-compress reduces the size of a CD image file (ISO, BIN, CDI, NRG, CCD or any other format that uses raw sectors) by eliminating the
Error Correction Codes (EEC) and Error Detection Codes (EDC) from each sector when possible.
Since the data ecm-compress strips is usually nearly impossible to compress with traditional tools, the resulting ECM file will compress
far better than the raw CD image.
Hard drives already have mechanisms to protect data integrity, EEC/EDC data can thus be discarded safely.
This data can then be generated again using the command ecm-uncompress.
Because ecm-compress only discards EDC/ECC data for sectors where it's verifiably possible to recreate that data, the process is lossless.
In case of copy protection, ecm-compress will preserve the bogus data.
EXAMPLES
ecm-compress foo.bin
strips the ECC/EDC data from the foo.bin CD image and save the resulting file as foo.bin.ecm
ecm-compress foo.img foobar
strips the ECC/EDC data from the foo.img CD image and save the resulting file as foobar
SEE ALSO
ecm-uncompress(1).
