Yeelight W3 lost its colors after 1 year of use, just the white LEDs work

My W3 light bulb started losing it’s colors after 1 year of use.
First I lost the red color, By cherrypicking the red color on the app it used to turn off instead, yellow was green, purple was blue etc.
Later, blue color was lost and just the green color remained.
Now even the green color is gone, All that is left are the white LEDs.

Anyone got this problem? is this fixable? I have an old broken yeelight 1S here, can I reuse their colored leds on my W3? are them the same?

Unfortunately I cannot find W3 for sale anymore, so I plan to try to fix it.
