Wording on the 2IS reads xx.x psi w/5 passengers 825lbs.
Implying max load and cold pressure setting.
Like yours, it does not offer a minimum load/psi. Likely confusing for some?
Obviously the tires choosen should exceed the cars maximum load per tire. That said, many read the tires Max PSI which is the wrong information. Well unless the tires max load matches the cars max load. Then the pressure may be correct.

Would you be able to provide a pic 2013FSport?

True and I'm aware. So what does the 3IS door sticker say? Fully loaded? Very likely.
My point remains the same. 85% of these cars run around empty (driver only) the rear tires over inflated, and then bald in the middle prematurely from over inflation.
Except for those who only check every 9mo. Whereby it goes from over to under inflation. lol

I think based on what I read on your sticker, the recommendation isn't for a fully-loaded vehicle. It just says that 825 pounds is the maximum allowable load. It doesn't say the recommended pressure is for 825 pounds.

It would not make sense for them to give the recommended tire PSI based on max capacity since as 2013FSport stated most people aren't at max weight and if they even do get close it's probably a few times a year.

The "Loading" information is how much you can put in the vehicle...or load it with.
The "Tire" information is the recommended pressure for the tires...but has no bearing on the load that's in the vehicle.
Using the recommended pressures will not see the rear tires over inflated just because there is no load in the rear.
And yes, could the pressures be adjusted for load? Sure...but it's not like we're towing a boat and loading the vehicle beyond it's capacity.
To adjust the pressure just for putting 5 passengers in the vehicle would be a little abnormal.

I'd think our goal here is the same, to get the maximum miles from our tires. That said, keep an eye on them and adjust as needed to achieve even wear (proper inflation). This could be +/- 4psi variant at each end depending on how the vehicle is used.
For those who actually check pressure monthly and run it at the listed pressure, do report back your tire wear after 20,xxx mi. Lets see who has even tire wear and who blew the center tread from their rear tires.
Disregard above if your not checking it yourself.

Parking in a garage makes things interesting, too. In my garage, in winter, I typically run 36 or 37, since the pressure will drop a bit if I go park it somewhere outside. In summer, I typically run 35, since driving on the hot roads will make the pressure increase more. After a full day of sitting in the office parking lot, it can sometimes reach 38, even though it was 35 in my air conditioned garage. Something to consider.

This is the last season for the tires as they are evenly worn out.
The vehicle has 76,000+kms on it and I check the tire pressure myself as it does not have a readout on the dash.
I keep it at the door sticker recommended pressure and the centers are not worn out unevenly.
I won't comment about my IS cause I don't have the factory wheels or tire sizes, so the door sticker is a moot point.
I've owned a boat load of Toyota's over the years, and for all the ones that retained the stock rim and tire fitment, I've never had any wear down the center using the door sticker recommended pressures.

we can cut down on emissions/consumption massively as a population by just keeping tires inflated properly. 35 to 40 is ideal for this.
