100% this. It's honestly pretty similar with the real amp, I think anyone struggling with the QC model would probably need to take some time with the real thing to get it recording well too. With the real amp someone is likely to run the master lower anyway, and they'll have a bit more motivation to persevere with it - with a modeller there is no real perception of how loud the amp is, and its so easy to just move onto another amp if its not sounding right. I haven't spent a great deal of time with the QC model but my friend with a QC complained about the model when he brought his QC over to me - we dialled in the QC model compared to my amp and got them pretty much identical (using a load box). From that point on he stopped using captures of rectos and just used models so he could dial them in himself. Pretty sure since then he predominantly used models over captures.
It's EXACTLY the same thing with the Helix and Amplitube models, and likely many others too. If the default master volume setting is too high, it's usually the last one most people think to address when really it's the one that sets the overall voicing for the amp. For basically any high gain amp its really critical to make sure the poweramp has enough headroom as the low end and fizz are the first things to go if things are driven too loud.
I really wanted to try and avoid these tests turning into an IR discussion but just because people are asking, this is the IR (for both 5150 and Recto tests). For the VH4 test, I used position 34 (its very slightly closer to the centre of the cone).
