Missing RGB/HSV options for FRITZ!DECT 400

[Baspla]

Hi i wanted to set my FRITZ!DECT 400 to a custom color but there is no way to send hsv values.
As can be tested using the Fritz Smart Home App, you can set other color values than the default on a FRITZ!DECT 400 using the app.
Is this a recent change, or is the API tied to the defaults, while the app isn't?
