Yeelight LED Bulb Color 1S has unsaturated colors

Hello.
I recently purchased a Yeelight LED Bulb Color 1S and when I went to switch to the color option, only the Red, Green and Blue show strong color tones. i have a Yeelight LED Bulb Color || and the colors are more vivid than the newer bulbs. if this is a firmware thing i ask you to PLEASE correct this because the colors are terrible on this bulb.
