R19 Polar Pak Insulation

I opted for the R19 Polar Pak Insulation option on my 2018 BS.

I am working in the media cabinet trying clean it up, and it is very hot in there, even with all devices off and the door open! Touching the ceiling with a thermapen shows 105 degrees. Touching the ceiling right outside of the media cabinet shows 96 degrees.

Is this normal? I sort of expected better performance up there understanding that it takes most of the brunt of the solar/heat.

Behind the media cabinets is a wooden box where they have run some vents, not sure where the air is coming from or if they are just fans of some sort. I'm guessing there is no insulation there? The shade covers half of the vents anyway, so not sure what purpose they are serving.

Behind the back panel of that cabinet you may have your windshield defogger air blower going with hoses to the ceiling vents above your windshield.
If panel opened you will see wiring for running lights speakers and other wiring, insulation may have moved above it to draw air for blower.
Look in this link.
