Been working on mainstream cars with them since 2018 at least (1.0 t-gdi hyundais for example). And the first MG HS of my gen was released in 2018 with a GPF aswell. And they were not the first ones to have them

I was referring to cars in the United States. I know outside of the US, cars have had them for quite a few years at this point.
I have not come across a direct injection engined car with clean tailpipes without GPF though. unless still in the showroom.
My Mazda's tailpipes stay way cleaner than I ever would have thought for it being DI without a GPF. I will need to take a picture when I get a chance.
wipe your finger around the inside and take a pic of that
In my experience DPF's have been very reliable. I've always suspected when people have had issues that they are a symptom of a bigger problem. Often you hear of people replacing their DPF 2-3x before getting it removed as "they are so troublesome" and then when it is removed you find the engine smokes, likely due to worn injectors, boost leaks, tired sensors etc. Then you start to wonder exactly why the DPF was blocking up all the time...
I see no reason why GPF's wouldn't be as or more reliable.
I used to 'delete' all my cars when I was younger and now I'm quite disgusted I used to do it.

This is after 31k miles. The amount of soot in the exhaust seems pretty minimal, definitely some but overall very minimal.
DPFs are definitely more reliable now than when they were first implemented. I agree DPF failures are almost always something else failing first which causes the DPF to plug, whether that is a sensor failure, an injector leaking, or boost leaks. GPFs should be even more reliable than a DPF given the different operating conditions of a gasoline engine vs diesel engine.
yes that's very minimal, but still more than a GPF equipped car should/would have. Though to be fair, it could just be dust
