How much does display calibration factor into this? I'm fairly confident it must impact the results, but unsure how much error it would introduce.
all my displays were so well defined out of the box, it wasnot worth it at all. Like you would need to use this particular profile for proper real industry printers to even have any benefit of it if even because all my displays were well calibrated.
I would argue that this would only make sense for highly profesional graphics designer and i don't think this experiment requires this level of granularity.
The last few generations of most everything have been rated "Visually Indistinguishable From Perfect", so it seems they don't test as much anymore.
