Dell 14 Pro Plus PB14250: Display colors totally off

My employer switched the IT equipment vendor from Lenovo to Dell. I received a new work laptop Dell 14 Pro Plus built in 2025. So far so good.... When starting up the laptop it first displays the Microsoft Bitlocker screen which basically only shows a blue colored background. I noticed that the Dell display only rendered a pale blue color, far less brilliant than my old Lenovo X13 built in 2020. Then it got worse: our Windows desktop screen which mostly consists of red colors (bright to dark red) is rendered in a pale/brown orange/red tone, not comparable with any other IPS color display. I have never seen such a bad computer screen in the last 15 years since IPS panels became the standard. It seems that the display colors cannot be calibrated via Windows, also the Dell RGB self-test (system start with key "D" pressed) does not improve on the red color. Local Dell service sent a technician who replaced the original panel but the replacement display is of the same bad quality showing the same kind of colors.

Our office IT support basically tells me that the Dell 14 Pro Plus is kind of an entry-level laptop with a bad display and that this is how Dell markets its products. They want me to upgrade to an executive model which according to them has a decent display built-in. I do not believe that Dell would equip its models in 2025 with such bad quality displays; each 300$ competitor model has a better screen. Are there better panels available for the Dell 14 Pro Plus model or am I stuck in a time warp with a display from the 1990's?
