I think so; I prefer the white in the W as to the gray. Getting rid of the light blue is a good idea... i find my eyes naturally looking at the light blue due to the brightness.
I'm not too big a fan of the oval period in A but I think the circle period in B is a little too big.
The round period (in B) is a better shape than the oval (in A) but I don't understand why you need it. A single letter in a logo is almost an abbreviation by default. Putting a period in there is redundant and just clutters it up. It's typography dandruff.
