2017 F150 Limited SYNC 3 Build: 3.4.22048 seems to be missing features

I feel like I am missing features like the calm screen and I am not sure why. Everything hardware related is factory. I have enabled the calm screen with Forscan but I still do not see it.

Calm screen should be under settings → display. Note that for this option to show up you will need to have a certain firmware level on the APIM. You can read more about that here: Updating APIM Firmware (Calibration Files) - Ford - CyanLabs Official Community

Is it possible to make my dash and radio look like the newer trucks or am I missing something?

Radio should look the same as everyone else, except for station logos (depends on region). The new Sirius XM player/interface will require new radio hardware and is not available on older vehicles with stock equipment. Your dash (I’m assuming you mean IPC), will remain the same as stock. Any new IPC firmware you apply will likely only provide stability and bug fixes.

My biggest concern is flashing the wrong firmware and bricking anything.

Flashing new APIM firmware is probably the riskiest procedure here, older units are quite finicky. A 2017 should be relatively stable for firmware updates, but you never know. If all you want is to get calm screen working, I personally don’t think its worth the risk.

I have done the Fmods usb jailbreak on it

As for the jailbreak that is not something that is discussed on the forums here.
