Is there a risk of passenger screen burn in if I replace the default screen saver with a relatively bright image?

 

Virtually none.

 

Is the passenger screen OLED?

 

Yes. See The MBUX Hyperscreen | Future Vehicles | | Mercedes-Benz USA (mbusa.com)

"Key Highlights

• 3 separate screens, one 56” surface, with two-coatings of scratch and reflection-resistant aluminum silicate glass
• OLED technology – including a 17.7” Central Display and 12.3” Passenger Display
• 8 CPU cores, 24 GB RAM and 46.4 GB memory
• The largest display ever in a production Mercedes-Benz
• Haptic feedback with a total of 12 actuators under the touchscreen surface
• Supports 27 languages with Natural Language Understanding (NLU)"

 

I see, thanks for information. I am not sure what type of OLED it is using, some type of OLED burn in quicker than the others. ie. AMOLED vs OLED etc. etc. but I do agree with the other forum member of the burn in risk being virtually none.
