Could these be fake TY (or botched batch of real TY) ?

After reading about TY media as the best media to use
I bought 100 CD pack of these ( being sold as "CD-R TAIYO YUDEN Blank 700MB 48x 100Spindle" by Emgeton )
and their quality seems to be very low.

There are visible defects in the material:1-3 (sometimes even 15) small holes or bubbles(?) in almost every CD.
If viewed from angle small rainbow circles can be found around the defects and sometimes rainbow spikes stretching towards the outer side of the CD.
And yellow graph areas seem to correspond to the location of bigger defects in media.
Media from other manufacturers burned on the same day are OK, so it should not be a burner problem (LG GCC 4521B fw 1.07, Nero 6 with latest updates)
