It is but not as visible. 

If the output filters are less than correct it gets worse.   Also if you pushing
power the LPFs will show heating effects remember 10W max even then
your pushing it.  

CW mode is a square wave driive so the harmonic content like previously
discussed is about 20db greater than for SSB not push to clipping
