My limited's seats look similar to that without it coming off except the bolster is a slightly differnet color and has a much rougher\course feel to it, and matches the rest of the seat except the bottom and middle back where your back goes.
OP has the same dash material I have, it doesn't feel like leather, but not cloth nor vinyl (feels closest to vinyl though)
I have used leather cleaner on everything and it has not damaged the material so far. There might be something better to use but leather cleaner goes a long way
I could see a Limited having differnet\higher quality seats then an TRX even if you don't want to believe that. TRX doesn't have all the options a Limited 1500 can have, it is a differnet alternative trim to the Limited not a higher level trim. In fact those seats are DIFFERENT then my 22 Limited. Note how it has holes on the bolster as it curves in, mine does NOT have that.
This is my front driver seat

This is the odd material on my dash which is super smooth (and feels differnet in the middle)
