LIFX Mini Color updates

Got some LIFX Mini Colors to play with. Compared to LIFX Z it looks like colour updates have some kind of built in delay while colours are transitioning gradually. Result is similar to using duration-parameter in SetColor-message, but my duration is set to 0. Does Mini have some kind of built-in blending time for colour changes? With LIFX Z changes happen immediately without any delays or blending if I set duration-parameter to 0.

Interestingly LIFX app can do strobe effect with very quick updates. I can reliable update Mini around 10 times per second, that is much slower than what LIFX app achieves. I even tried using waveform-messages for (quick) updates but waveform-messages do not seem to function as documented.
