nobody knows how the CW / WW is generated?
The question is the W channel Warm white or Cool white?
Obviously one of the 2 (likely cool) is a combination of colors. Therefore the actual white LEDs would Warm.
But the possibility is that it’s cool white as white channel and uses some red-green to warm it to a yellow tone.
The type of W led makes the difference on which strip to buy.
RGBW or RGBWW
