In answer to your question about lesser loads reducing gas pressure at the receiver, I doubt it.
The reason I say this is that you couldn't low load the Grendel enough to make a noticeable difference. Take the 9mm calibre for example. It's only about 4-6gns of powder and yet when suppressed can spit a lot of gas in your face. The H&K K 9mm,when suppressed spits gas and crap back in your face through the ejection port. If you are a left-handed it's even worse. Eye protection is compulsory or it's like getting sand thrown in your eyes. The H&K SD however with its dedicated suppressor is totally different, no sense of excess gas or sting at all. These examples are also relevant because all the gas coming back into the receiver is from the chamber, not the gas system. No gas system in the H&K MP5 9mm, it's all roller locking delayed blowback.
In your case you won't change the amount of soot coming back into the receiver and onto you by loading less powder. You won't notice the difference. I do however recommend you choke off the gas somehow when using a suppressor, or that gun will be getting hammered every time you pull the trigger.
I fear you are correct sir
