Just mentioning that because the max/limit resolutions on photos and videos are different but you started talking about video resolution then switched to photo mid-paragraph 
My phone (a 2025 higher-end Samsung) takes up to 8K video, but it takes photos up to 50MP, which is a higher pixel count than 8K (33.2MP)
Also 6K as a resolution, while it can be mathematically calculated (5760×3240 pixels, for roughly 18.7 million pixels aka 18.7MP) is not really a 'thing', there's 4K and 8K TV's, there is not and will likely never be a 6K TV (though there's a couple PC monitors that are pretty close to "6K" ).
What I'm on about is there's not really an excuse/explanation along the lines you are (generously) offering for IQ47 that makes much sense. I think what's happening is Pathological Narcissists have to come off like they know everything about every subject they're asked about. Add the symptoms of FTD (tendency towards confabulation being a primary symptom) to his NPD, and we get these jumbled stews of utter bullshit.
IOW I think it's not a mistake, as such, he's just a narcissist and confabulator, compulsively pulling nonsense out of his ass
