Display lighting

Hello everyone, I’m new to the Motor Talk and I have a question to the Grandland X owners. I bought a Grandland X from the Opel dealer in December 2020 Year of manufacture/first registration June 2019 it innovation equipment. I noticed that the illumination of the external temperature indicator in the touchpad appears darker on the top left than all other displays like zb time etc. Since the warranty expires next month I was at the fOH which informed me that this is normal. The outside temperature display is made or appears in the same brightness as the other display information in the upper bar. Many thanks Dieter
