Paulmann 500.4x led drivers don't support "x":0.701,"y":0.299

What happened?

See also #13840 and #6059 - if you set the light to RGB 255,0,0 (pure red), home assistant requests this as "x":0.701,"y":0.299. The led driver seems to ignore this. Z2m does report this value as set. If you use Z2M qui to set pure red, the value used is x": 0.7006, "y": 0.2993 (which coincidentally other colored zigbee led bulbs seem to report back as set value when "x":0.701,"y":0.299 is requested)
I have tested with a paulmann 500.47, the mentioned ticket seems to have the same issue with a 500.49.

What did you expect to happen?

I expected color red to be set

How to reproduce it (minimal and precise)

Pair a paulmann led driver such as the 500.49, and set eg {"state":"ON","color":{"x":0.701,"y":0.299},"brightness":254}. The state will not change.
