BMP and PNG are Lossless, so you are comparing Apple to orange.

The point is assuming all these alternative to JPEG can only do 30% improvement comparing to 1MB JPEG pics, in Web Scale, and Browser with an extremely long road to have these implemented, may be bandwidth will outshine what ever work being done. That is of course not saying alternative arent good, it is just we may have even BETTER alternative down the road.

Much like how bandwidth has improved, AAC or MP3 didn't matter much any more. We can all afford 192Kbps Streaming, and even more so once technology improves even more. We choose AAC not because MP3 is much worse, but it has its own problem like clipping and continuous playing that is inherent in the codec. Much like JPEG doesn't support Alpha Channel that cant be fix without a new codec.

That is why you see the next biggest option poll in the picture format is JPEG sticking around. Alpha Channel is mostly a web problem. For lots of other people bumping up a little more bitrate will do. Storage Price is cheap, and will only get cheaper. The roadmap for HDD wasn't clear enough before, as we have doubt on HAMR technology ever working. But WD MAMR is much simpler solution that offers up to 50TB per HDD. We have Massive MIMO that offers 3 - 5x capacity improvement, and more from LAA, 5G with NR and mmWave offers much more capacity, it is not hard to imagine your mobile phone will have a consistent connection with at least 100Mbps performance in 5 years time.

We need a alternative for Jpeg, sure, but I dont see a clear winner yet. Not one with performance, patents and other benefits that outshine Jpeg.

We have AI and machine learning improving Opus quality even more, that is in nearly 20 years with numerous codec promising mp3 128Kbps quality at 64Kbps, we finally might have one. And it is royalty free, and still Opus is not widely supported, yet.
