alt Hacker NewsEXR stores the color-space information differently, and you missed the point.
Have a look at a tutorial that dives into the basic details, and consider learning something:

PNG has its use-cases, and some people do expect that baked color-space garbage look given it dominates a lot of low-end media. Have a great day =3
I'm trying to follow your point. But...there are problems with your claims. Yes, EXR stores color-space differently than PNG. Because EXR doesn't store color space at all.
In the first video, the person loads the image and manually chooses a gamma transfer function with 2.2. If that was then saved, it would produce the washed-out fireball you mentioned.
In the second video, the person loads the image and manually chooses rec.709, which is also gamma tf and also produces washed-out fireball. In fact, the EXR image he loads literally has a bright fireball and you see it get washed out.
If you want to make claims about EXR being better than PNG, you need to say why storing the values as floating point is better than integer. But the blown-out fireball example is just incorrect. As evidence, I'll point to HDR. ANYTHING you see in an HDR movie is now 100% losslessly reproducible in a PNG.
