In general, with some applications people hit the limits pretty quickly with PNG and JPG. In our use-case, the EXR format essentially meant a rendered part of the source image wouldn't be "overexposed" by the render pipeline, and layers could be later adjusted to better match in Resolve. Example: your scenes fireball simulation won't look like a fried egg photo from 1980 due to hitting 0xFF.
If you've never encountered the use-case, than don't worry about the aesthetics. Seriously, many vendors also just don't care... especially after they already were paid. Best of luck =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.
