That's actually pretty neat. No white patches are not normal for either combo.
HGW Enchis have will show some calico-ish white coming up the sides, very similarly to your pastel enchi. It's one reason it's one of my dreams to produce one! They're so cool looking as adults and babies! I'm not a fan of the NERD "enchi hgws" on WOBP right now (mostly because I don't think there's enchi in any of the NERD photos), but the last one by Matt Lerer is a pretty cool example of a baby. Try googling around for an adult photo, because they're pretty awesome with the white patches

The firefly looks like a BlkEL paradox of some sort, but I find it strange that it appears to be scraped along the body, rather than how paradox spots typically look on BPs.
