IMO, for what it's worth, the first photo looks like it's right side up and it looks to me like
K 2 rows with blue,
*then (K3tog, Yo) in white all the way across.
Then K back across in white, but KPK in the stitch that was K3tog to get back the stitch count.*
Then change to blue and repeat the last two rows.
Continue in alternate colors.
I can see that sort of. It would take a swatch to be sure.
