They've said that in at least a few videos and it's completely true. At least when viewing on an iPhone 13 screen I mostly can't see any difference in PS5/PS5 Pro IQ comparions without lots of zooming. But on a 27in 1440p monitor the Pro is obviously superior with no zoom at all, even in the compressed videos and screenshots I've seen. This might have contributed to the Pro's poor reception. People watch the reveal on their phones, think "it looks the same", then they show it zoomed and people think " yea but I don't play games at 300% zoom". Well you also don't play PS5 games on a phone but that point is somehow lost.
