So far as I am aware it will not make any difference, your green card is the important document. My understanding is that the requirement for machine readable blah blah depends on the date of issue of the passport and is specifically in regard to visitors as opposed to permanent residents but hey I have been known to be wrong before

Edit to update

U.S. Lawful Permanent Residents (LPRs)
must provide one of the following:

I-551, Permanent Resident Card (“Green Card”)
Machine-Readable Immigrant Visa endorsed with a CBP Admission Stamp
Temporary Residence Stamp (ADIT stamp) contained in a passport or on Form I-94
Valid Reentry Permit
Unexpired Immigrant Visa
