My MBP also gets blue screens upon wake up (only when I open the lid, if it was open prior to desktop it pops me straight to my desktop) and even then, its pretty uncommon. I wouldn't worry.
A Kernel panic is when, seemingly for no reason at all (trust me, there is one😉 ) the screen dims and a grey box pops up saying, in about a million different languages, "you need to restart your computer press and hold the power button, blah, blah."
MUCH nicer and happier than a BSOD!
