WOC quality 2017 stock

Hi guys just bought my first YSL - the small WOC :smile: I've been reading about quality issues with some of the wocs from past seasons on this forum and heard a rumour that YSL had changed the leather supplier to counter this issue (2017 Q3?). Anyone had any experience with this? Also how do I read what appears to be the date code on the white card? For mine it says 2017 3 07098 and then a bunch of other numbers and letters.
