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.

There is a lot of conflated contexts to unpack there...

However, I still trust the ILM engineers over your pet project, and maligned post that reeks of LLM slop.

The argument of making cow from hamburger doesn't hold true under our use-cases. You were shown the path, and it is your choice to put in the work to learn something important.

Best of luck kid =3
