I usually set mine to 4K on my less-than-4K retina display anyway, just for the higher bitrate. It doesn't really make a particularly perceptible difference on some of the more modern codecs, but on some services it can be more noticeable.On mobile devices it would make very little difference but for quality monitors or TVs I could see it being beneficial. And to think, people wanted an 8k iPhone this year ha. It’s all compressed to hell and back anyway.
I mean, didn't Google run gigabit fiber through half of the country? The fact that they are complaining about bandwidth limitations just feels cheap.They stopped "remembering" a 4K setting a while back, citing data throughput restrictions during Covid as an excuse. I certainly won't pay $$ to toggle each and every video back to 4K on Youtube.
