That's the WORST, isn't it? Are they all from exactly the same print batch?
That's likely to be a soft-proofing issue, not a calibration one. I'd ignore that print at this stage.
I have calibrated an M1 with my X-Rite. And the new Spyders (the SpyderX range) will do it fine too.

Now that we have a proper raw edit with all the channels intact, it's time to talk about how to edit it without causing clipping again.
Needless to say, this is very tricky. Clipping happens very easily with these colours.
I'm not saying it'll be WAY more pixely.
I'm saying that you should try to physically see the monitors you're considering. I know it's convenient to buy online, but I don't think it's smart in this case.
