ECW to ICO: what to expect from the conversion
ECW describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the ICO afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after. ECW carries 16 bits per channel and ICO carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end.
